The role of government –
YVONNE HARVEY
Contributor
KNOW you have all been enjoying the
discussions on exam-type questions that I have
been presenting over the last few weeks. For
this week, the question is a Profile 3 question
based on the role of government. As usual, I
encourage you to revise the area first and then
attempt the question before looking at my
guidelines and answers. Here’s the question:
I
Profile 3 questions
Protection of the environment is also a
responsibility of the government. There are laws
against the dumping of waste and zoning laws
that indicate the geographical locations in which
industries are allowed to be set up.
(C)(I) - (III) GUIDING YOUR THOUGHTS
Taxation is the process of paying a tax or taxes.
Governments require taxes for a number of
purposes or we can say that taxation has a
number of roles.
(a) Define ‘government’. (2 marks)
(b) Outline three responsibilities of government
in an economy. (6 marks)
(c)(i) Define a ‘tax’. (2 marks)
(ii) State two purposes of taxation. (2 marks)
(iii) Distinguish between progressive and
regressive taxes. (4 marks)
(d) Discuss the impact of government provision of:
(i) Health care
(ii) Education (4 marks)
Total marks: 20
ANSWERS
(i) A tax is a compulsory payment made to
governments. It provides a major part of the
government’s income.
(ii) One purpose of taxation is to redistribute
income from the higher income groups and to cut
down on the importation of goods and services.
Also the provision of social services expenses
comes from taxation.
Now that you have answered the question you
can have a look at my guidelines for the answer
and the example of an answer.
(iii) Progressive taxes are taxes that rise as the
income rises, not only in amount but also in
percentage. It reduces the income of the higher
incomes substantially. On the other hand,
regressive taxes take a smaller proportion or
percentage of larger income earners than smaller
incomes. Taxes on goods and services are by
their nature regressive.
(A) GUIDING YOUR THOUGHTS
Think of how a government comes about and
what it does. This can be used to define them.
ANSWER
(D)(I) AND (II) GUIDING YOUR THOUGHTS
Government can be defined as a group of
appointed officials whose duty it is to carry out
the will of the people as expressed in Parliament.
This part of the question requires that you look
at how certain provisions by government affect the
country.
(B) GUIDING YOUR THOUGHTS
ANSWERS
Think about some of the main or overall things
that a government does for other economic agents
in the economy. The syllabus lists a number of
roles of a government. See page 28.
In terms of health care, provisions by the
government ensure that a population is healthy
and does not get sick. Such a population will be
more productive and this will benefit the country.
ANSWER
One of the responsibilities of a government is
the security of the state. In this responsibility, the
government must ensure protection of the country
from attack by other countries by providing army,
navy and air force protection and by attempting to
keep a peaceful working relationship with other
countries.
The government is also involved in the
protection and general welfare of the citizens of
the country. This involves protecting the rights of

citizens by passing laws and enforcing them
through the provision of the police, etc. It also
protects citizens by providing social services and
infrastructure to benefit them.
YOUTHLINK MAGAZINE | MAY 7-13, 2013
The provision of education ensures that the
population is numerate and literate and that it is
developed at different stages. Education is
subsidised or free and this cuts down on the cost
to individuals and so more persons can access it.
My friends, we have come to the end of this
lesson already. Remember to look at other
questions from past CXC papers and also the
ones in your textbooks. Bye, until next week.

yl:history
Preparing for the exam
DEBBION HYMAN
Contributor
I GUYS, the history examination will consist
of two papers – Paper 01 and Paper 02.
Paper 02 is a written examination and you
will be required to answer three questions; one from
each section of the syllabus. The questions that you
will answer will be based on the themes for which
you have prepared during classes. Paper 01 will
consist of 60 multiple-choice items. These will
cover the 10 core topics as outlined on the syllabus.
H
By this juncture you should have started studying
for your examination. This week’s lesson will focus
on skills that you can incorporate that will make
your exam preparation easier. Below are some
helpful tips:
Know your best learning method. People learn
in different ways. It is best to figure out which way
you learn best. Perhaps you learn best by seeing
words and concepts in front of you. If so, then
writing a lot is a good way to study for history.
Create illustrations of historical concepts. For
example, if studying about the layout of a typical
18th-century British-Caribbean sugar plantation
and how it displays self-sufficiency, you could
create a web map/semantic map in which you detail
the information you would provide in such an essay.
This will result in you developing knowledge in
your memory. Also, you will probably end up with
lots of notes from which to study. Visual learners
benefit from writing things down as it helps them to
remember better. This, in turn, helps them perform
better on tests.
If you are an auditory learner, it is best to
study using audio notes. For example, you could
record any important historical terms, events and
concepts on a sound recorder. You could then
schedule in your study time to listen to these
recordings. If you are a tactile learner, use flash
cards to study for history exams.
PREPARING FOR THE MULTIPLE-CHOICE
PAPER
Studying for a multiple-choice exam requires a
specific method of preparation which is distinctly
different from an essay exam. Multiple-choice
exams ask a student to recognise a correct answer
among a set of options that include three wrong
ones (called distracters), rather than asking the
student to produce a correct answer entirely from
his/her own mind.
To prepare for a multiple-choice exam, consider
the following steps:
Begin studying early. Multiple-choice exams
tend to focus on details and you cannot retain many
details effectively in short-term memory. If you learn
a little bit each day and allow plenty of time for
repeated reviews, you will build a much more
reliable long-term memory.
Pay particular attention to fundamental terms
and concepts that describe important events or
features or that tie related ideas and observations
together. These are the items that most commonly
appear on multiple-choice exams.
As you study your class notes and your
assigned readings, make lists and tables.
Concentrate on understanding multistep processes,
and on ideas, events, or objects that form natural
sequences or groupings. Look for similarities and
differences that might be used to distinguish correct
choices from distracters on an exam.
Do not simply memorise a book or your
teacher’s definition of a particular concept. Rather,
rephrase in your own words as this will result in
you really understanding what the definition(s)
mean.
Practise on sample questions if you have
access to a study guide or past exam papers.

I, STUDENTS! Examinations are here and I hope you are all
ready, having prepared well for anything that CXC ‘throws’ at
you. Briefly, let me remind you of a few things. In A
Midsummer Night’s Dream the themes include love, love’s difficulty,
dreams and magic. The love potion is integral to the way the play
develops and ends. The workmen who dramatise a farcical tragedy to
celebrate the duke’s nuptials cannot be overlooked as well. They bring
humour and underscore in their choice of drama the underlying
darkness of this play. Please pay close attention to the way the women
are treated by their male partners.
H
In Old Story Time, we find colour and class prejudice, superstition,
friendship and love. Please remember that in the drama section of the
exam you will be able to choose one play on which to answer a
question.
The English literature exam consists of two papers. Paper one is
the one we call unseen because the questions will be set on a poem
and a prose extract and a drama extract that you are not likely to have
seen before. There will be 15 short-answer questions and all are
complusory! There will be 20 marks for each genre/mode – so a total
of 60 marks will be allocated to this paper, which will contribute 36
per cent of the whole exam. You will have one and a half hours to
complete the entire paper.

Study
time!
Paper two has 12 essay questions. This is a change from last year’s
as well as the January paper. The paper is divided into three sections.
Section one deals with drama. There are two books, A Midsummer
Night’s Dream and Old Story Time in this section. Two questions will
be set on each of them and you must answer one of the four. Thirtyfive marks are allocated for this section and each of the other two
sections from which you will answer questions.
Section two has the poetry questions. Here, you will be given two
comparative questions to answer one. Please remember that in
responding to a question on poetry, you need to use information from
two poems.
YOUTHLINK MAGAZINE | MAY 7-13, 2013
The prose questions are to be found in section three. Here, there
will be six questions. You must answer one. There will be two on
Songs of Silence, two on the Wine of Astonishment and two on the
short stories, one of which will be named.
Overall, you must do three questions on this paper, each worth 35
marks. In addition to the 25 marks which will be awarded for content
and argument, a maximum of 10 marks is allowed for structure,
development and competence in the mechanics and language.
Please make sure to brush up on your knowledge of literary devices,
including your ability to recognise the writer’s purpose in using them.
Remember to organise your essays according to the way the questions
are set, without skipping lines or putting down your information as if
you are making notes. You will be writing essays. This means that for
each question that you answer on paper two you should begin with an
introduction, then three or four paragraphs in which you develop
separate points as required, then you should close with a conclusion.
Do not wait until you get into the exam to categorise the poems and
short stories. Please do so now if you have not done so already. By
this I mean group or classify them according to their themes. You
would, for instance, put God’s Grandeur and A Stone’s Throw together,
concentrating on the ways in which they are alike and those that show
that they are different. Stick to the works on the present syllabus. Now,
go into the exam room and do your best! God bless!

More questions on
patterns of inheritance
MONACIA WILLIAMS
Contributor
ELLO AGAIN, students! How are you this week? I intend
to complete the question we started last time. I certainly
hope that you used the opportunity to write your own
answers to the parts of the question that were not done. If you
did, you can now see how your answers compare with those
with which I will provide you.
H
We will begin at part (b) where we had stopped.
(b) Selective breeding programmes are deliberately used to
control the characteristics of a population of organisms. This
process is called artificial selection.
Explain how this process is different from natural selection.
What do you need to know to answer? You need to know the
meaning of the terms ‘breeding programmes’ and ‘natural
selection’. The introductory statement has provided you with
information that can be used in writing an answer, since it
defines for you the term ‘artificial selection’. Remember, too,
that artificial selection is also known as selective breeding.
Having refreshed your memory, let us put together an
answer:
Artificial selection uses human intervention to determine the
characteristic that is to be passed on or enhanced in future
generations. In natural selection, variation has to exist among
the organisms before the action of the environment can exert
pressure on the characteristic that is selected. The selected
characteristic that is passed on provides the organism with an
improved chance of survival, because it makes it better able to
survive the environmental change that exerted the pressure. In
artificial selection, the characteristic that is selected to be passed
on does not usually have anything to do with the environment, it
usually does not give the organism any survival benefit and it is
usually some characteristic that is beneficial to man, for example
crops that grow faster, have greater yield, cows that produce
more milk, cows that produce more and better quality beef per
kilo of feed. In artificial selection, the process is fairly rapid,
while in natural selection the process is slow.
(c)(i) Genetic engineering is used to change the
characteristics of organisms. How does genetic engineering
differ from artificial selection?
(ii) List two concerns people might have about using genetic
engineering to alter characteristics of organisms.
LET US LOOK AT SOME POSSIBLE ANSWERS
If you are not careful, you might confuse artificial selection
and genetic engineering; but if you remember your theory, you
will remember the difference.
humans.
The removal of a gene from one living organism and the
insertion of it into another.
QUESTION
ANSWER
In artificial selection, the reproductive process is involved.
Gametes are produced and are fertilised, naturally or artificially,
between the chosen organisms. Genetic engineering involves
manipulation, not at the gamete level but at the level of the
gene. It is the deliberate changing of the genotype of an
organism by humans. This means that new organism can be
formed from altering the genotype of a somatic cell that has
been altered.
(c) (ii)
The word ‘list’ in the question indicates that answers must be
short and to the point.
LET US SEE WHAT COULD BE WRITTEN:
The outcomes are not always certain.
The long-term effects of engineering are not yet known.
Genetically engineered traits could become transferred to
other related species.
Changes might be made to crops to benefit rich countries
rather than poor ones.
Humans might be tempted to develop organisms for their
own needs rather than the benefit of all.
You could also add any other moral or ethical issues;
remember that you were asked to give two, so do not waste
valuable time giving more. You will not get extra marks for
giving more than two. Make the answers brief and to the point.
I am now going to add a few other questions on genetic
engineering. See how well you can answer them.
QUESTION
(i) What is genetic engineering?
This is basically memory recall, it is asking for a definition. If
you have studied your definitions you should have no problem
providing an answer.
TWO POSSIBLE DEFINITIONS ARE:
The deliberate changing of an organism’s genotype by
YOUTHLINK MAGAZINE | MAY 7-13, 2013
(ii) Give one advantage of genetic engineering.
Any one of the following answers can be given:
Traits change more rapidly.
Individual traits can be targeted.
Any organism can be used, unicellular and multicellular
QUESTION
(iii) Suggest one problem that could arise from genetically
modifying an organism.
ANSWER
The new trait could cause the organism to react to its
environment differently by changing its niche.
(iv) Suggest one reason it is possible to successfully transfer
genes from one species to another, yet species under normal
conditions do not interbreed.
To answer this question you will need to remember your
theory. If you were successful in providing answers to the
questions above, this one should offer no problems.
Remember that the transfer of genes between organisms is
genetic engineering, and that genetic engineering takes place at
the level of the gene, and at this level all organisms are similar.
ANSWER
Organisms are similar at the level of the gene, hence transfer
of material can take place without problems at this stage.
The genetic make-up of organisms is similar at the DNA
level, hence transfer of material can take place here.
I hope that these questions have helped you to better
understand the concepts.
See you next week!

Our role in the
integration
process
MAUREEN CAMPBELL
Contributor
OBJECTIVES
1. EXAMINE THE role of individual citizens, business organisations and government in the integration
process.
2. Explain the role of regional agencies in the integration process.
ROLES OF CITIZENS
Citizens in the Caribbean region must be made aware that every member state in CARICOM must know
that they are not only citizens of a country but they are also members of the region. The integration process
is proving to be a major concern for the region as there are still conflicts that are reoccurring in the region.
1. Citizens must be informed of their role in CARICOM. It is the citizen’s responsibility also to be
cognizant of the culture, activities and other significant events happening in the region.
2. They must willingly invest in local and regional business, becoming great entrepreneurs.
3. They should support by buying goods produced in the region.
4. Show solidarity not only in their individual country but in the CARICOM region.
ROLES OF BUSINESS ORGANISATIONS
Entrepreneurs are very vital in the integration process.
1. They must ensure that there is good, striving, healthy competition in the region.
2. They should ensure the quality and quantity of goods and services produced so that they can compete
on the international market.
3. There will also be the need for businesses to have a wide choice of goods and have aggressive
advertising campaigns so that the CARICOM market can be visible on the international scene.
4. Businessmen must make use of opportunities for investment in the region. When this happens, loyalty
will be promoted and this will engender/encourage regional support.
5. There must be opportunities provided for investment and employment. Employment must be viewed as
one of the central role of the integration process, since it will make visible the contribution of citizens as
they provide goods and services.
ROLES OF THE GOVERNMENT
It is the role of the government to ensure that the citizens from the CARICOM community are given
greater recognition throughout the region. Work permits and qualification recognition are vital for the
feeling of oneness and cooperation.
1. The education of citizens about the objectives and benefits of integration must take place. Education is
the most effective way to bring about change as citizens and students are made aware of the benefits of
integration.
2. Heads of government must ensure that legislation for this process is void of all forms of
discrimination.
3. Policies must be enacted which will make it less bureaucratic for work and travel in the region.
4. The harmonising of policies/agreements will be beneficial to the integration process.
5. All protocols must be honoured, ensuring that treaties signed are observed and efforts made to think
about the region in spite of particular territories.
18
ACTIVITY:
Research and explain ways in which three of the agencies within CARICOM have recently helped or
responded to the needs of CARICOM citizens and with what success.

ELLO, CLASS! Last week, we examined
the skills needed to write a coherent
summary of an extended piece. This
week, I want to challenge you to use those
skills to write a summary of your own. The
extract comes from the May-June 2007 CXC
English A Paper 02. Follow the instructions
below:
H
Read the following extract carefully and then
write a summary of it in not more than 120
words and, as far as possible, in your OWN
words. Your summary must be in continuous
prose and in paragraph form. Only the first 120
words of your answer will be read and
assessed.
Since the beginning of civilisation, they
have served as marks of identification, spiritual
protection and decoration. Now, at the cusp of
another millennium, tattoos and other varieties
of body markings are resurfacing as a popular
form of individual self-expression.
Tattoos are timeless and can be as unique as
the bearers they adorn. They don’t fade away
like favourite T-shirts or get lost or broken like
school rings. They stay with you forever, until
death. They become a part of you from the day
you sit in the artiste’s chair, etching your
emotions alongside the needle’s sting,
transforming an instant of your life into a
symbol for the world to see.
Tattoos and other body markings arrived in
the Caribbean with African slaves and
indentured workers from China and India. They
were sometimes the only permanent keepsakes
of people snatched from their ancestral places.
The Caribbean’s original Amerindian
inhabitants also used tattoos to mark spiritual
milestones. The Taino of the North Caribbean
islands, for instance, used vegetable dyes to
affix images of their guardians on their skin.
These images also indicated an individual’s
lineage, or his or her social position. Each
tattoo was both a personal history book and a
mark of belonging.
Over the centuries, however, tattoos and
other forms or bodily adornments have
mutated, exchanging religious and cultural
significance for individualist associations.
Sometimes the mark of individuality has been
confused with rebellion and nonconformity,
often alluding to a stain of bad character.
Tattoo wearers seemed wild, dangerous, even
just plain bad.
Summary
writing –
combining the
main ideas
The passage is about the history and
significance of tattoos and other forms of body
markings over the centuries. To assist you to
write your summary, I want to highlight the
main points which can be identified in the
passage:
Tattoos are permanent markings which
have been around from the beginning of
civilisation.
They were bought to the Caribbean from
Africa, China and India, but the Amerindians
wore them even before.
They were used by people in the
Caribbean for religious, ethnic and cultural
practices.
Over the years, they came to be personal
expressions identified with rebellion and
defiance.
Attitudes have changed towards tattoos
and today they have become acceptable as
marks of uniqueness and difference.
Now I want you to combine these ideas,
rephrase them in your words and produce a
coherent summary. Before we wrap up our
discussions on summary writing, I want to
leave with you some reminders and guidelines
which must be followed:
Observe the stated length of your
response (normally 120 words).
Read questions for theme and specific
tasks to be done.
Read the instruction given and do not
assume that every year it is identical.
Recognise the fact that summary writing
comprises reading and writing skills
(comprehension and composition skills).
Appreciate some of the basic features of
summary writing:
- using your own words as far as
possible
- using standard English with
clarity and conciseness
- responding to the rubric of the
Delbert Gayle, captain of the Wolmer's Boys' School cricket team, shares a light
question with its implications for
moment with his principal, Dr Walton Small, and JIIC's Customer, Experience
audience, purpose and
and Innovation Manager Elizabeth Chung, after his team won the JIIC KO trophy
situation/context
recently.
- using connectives to achieve
fluency of writing/reading
- observing correct mechanics of
the language
But today, tattoos have come full circle.
Celebrities, writers, lawyers, housewives, all
proudly display their marks of rebellion. An
entirely new perception of the art of tattooing
has arisen, which is more than just a
preoccupation with style. The re-discovered
form of expression has spawned an entire subculture of individuals among us. They carry
this common bond of distinctions through
their daily routines. Via the images on their
forearms, shoulders, ankles, or torsos, they
connect to each other, announcing to the world
that it is OK to be unique and different.

Types of wireless media
NATALEE A. JOHNSON

OOD DAY, students. This is lesson 33 in our series. In this
week’s lesson, we will continue to look at data communication
and network.
G
A wireless network refers to any type of computer network that is
wireless and is commonly associated with a telecommunications
network whose interconnections between nodes is implemented
without the use of wires. Wireless telecommunications networks are
generally implemented with some type of remote information
transmission system that uses electromagnetic waves, such as radio
waves. Examples include:
(1) SATELLITE
This is man-made equipment that orbits around the earth or the
moon. It acts as a relay station in outer space. It accepts signals
beamed to it from a point on earth and then reflects the signal to
another point. It can transmit data that includes text, voice, pictures
and video.
ADVANTAGE
short distances from fixed and mobile
devices, creating personal area networks.
It can connect several devices,
overcoming problems of synchronization.
There are some other terms associated with communication of
which you may have heard before, such as bandwidth which relates to
communicating via a cell phone. Let us now examine such terms.
BANDWIDTH
WIRELESS FIDELITY (WI-FI)
This is a trademark of the Wi-Fi group for certified products based
on the IEEE 802.11 standards (which is an organisation dealing with
local area networks and
metropolitan area networks). This
certification warrants interoperability
between different wireless devices.
Wi-Fi is used by most personal
computer operating systems, many
video game consoles, laptops, smart
phones, printers and other peripherals.
This is a data transmission rate or the maximum amount of
information (bits/second) that can be transmitted along a channel.
TYPES OF BANDWIDTH
BROADBAND
This is the bandwidth that includes microwave, satellites, coaxial
cable and fibre optic channels. It describes a technology that provides
bandwidth that is greater than that provided by ordinary telephone lines;
that is, greater than 64 kilobits per second. It is used for very high-speed
computers whose processors communicate directly with each other. The
greater the bandwidth the greater the data carrying capacity.
HOTSPOT
A hotspot is a physical location that
offers Internet access over a wireless
LAN through the use of a shared Internet
connection and a single router.
NARROWBAND
This is a term used to describe data that is transmitted at a slow
speed (just over 10 characters per second), for example, telegraphed
transmission.
No distance limitation.
A router is a device in computer
networking that forwards data packets
to their destinations, based on their
addresses.
DISADVANTAGES
Very expensive to set
up.
Not suitable for rapid
exchange of data because
delays occur when data are sent thousands of miles up into space.
(2) MICROWAVE
These are very high-frequency signals that can be transmitted
through space. In this communication channel, the medium is not a
solid substance but air itself.
ADVANTAGES
Travels at the speed of
light.
Transmits both analog
and digital signal.
VOICEBAND
This is the bandwidth of a standard telephone line and it is used often
for microcomputer transmission; the bps is between 110 and 9,600.
COMMUNICATION MODES
The three basic transmission modes or directions are:
SIMPLEX
MODEM
The term modem is short for modulator - demodulator and is an
electronic device that can convert digital signals into analog signals
and vice versa. For example, a modem at one computer converts the
digital signals produced by the computer to analog signal for
transmission along a telephone line. The speed of a modem is
measured in bits per second (bps). The process of converting digital
signal to analog is called modulation, whereas the process of
converting analog signal to digital signal is called demodulation.
DIFFERENT TYPES OF MODEM
This is where data is transmitted in one direction. An example in
computing is the interface between the keyboard and the computer, in that
key codes need only be sent from the keyboard to the computer system.
HALF-DUPLEX
This channel can send and receive data, but not at the same time.
An example of this would be the use of a ‘walkie talkie’. Only one end
transmits at a time; the other receives.
DUPLEX
This is where data can travel in both directions simultaneously.
There is no need to switch from transmit to receive mode as in halfduplex. It is like a two-way bridge on a two-lane highway.
DISADVANTAGE
Cannot travel around
bend.
OTHER MEANS OF TRANSMISSION
Point-to-point transmission - this is a direct link between two
objects (such as computers) in a network.
Broadcast - this is the transmission of data to all connected
stations simultaneously.
(3) INFRARED
This is a wave of light that is in the area beyond the visible part of
the colour spectrum. While it is invisible to the human eye, infrared is
often used to enhance visibility when using night-vision devices.
We have come to the end of this lesson. See you next week, when
we will begin to look at terms associated with the Internet. Remember
that if you fail to prepare, you should be prepared to fail.

Alcohols and acids
FRANCINE TAYLOR-CAMPBELL
Contributor
IMPORTANT POINTS
Alcohols can be prepared by the hydration of alkenes.
Alcohols have the general formula Cn H2n+1OH.
Ethanol, a type of alcohol, can be made by the process of
fermentation. Enzymes in yeast feed on sugars, converting
them to alcohol and carbon dioxide. The percentage of
ethanol produced using fermentation cannot rise above 15
per cent since the ethanol poisons the yeast. To get a higher
percentage of ethanol distillation is used.
Ethanol is used as a solvent in the perfume industry, as
fuel in spirit burners or mixed with petrol to produce gasohol
to be used in vehicles.
Alcohol can modify the way your body functions. It is a
depressant and helps to dull the senses and slows down the
body’s reaction time. This can result in accidents.
Alcohol is also addictive and can lead to social and
emotional problems. When taken in large quantities, alcohol
can also damage the liver, leading to poisoning and death.
Carboxylic acids are generally weak and have the formula
Cn H2n=1COOH.
Alcohols and carboxylic acids combine to produce esters
which have the general formula RCOOR, where R is an alkyl
group such as CH3 and C2H5.
REACTIONS OF ALCOHOLS (USING ETHANOL)
1. Alcohols burn in air or oxygen to produce carbon dioxide,
heat and energy.
2C2H5OH (l) + 7O2 (g) =========== 4CO2 (g) + 6H2O (g)
2. Alcohols react with metals such as Na, Li, Mg and Ca to
yield hydrogen gas and to form salts called alkoxides. The
reaction is similar to the reaction of metals with water
because of the presence of -OH.
(H2O can be written as H - OH)
2Na (s) + 2C2H5OH (l) ======= 2C2H5ONa (aq) + H2 (g)
sodium ethoxide
3. Alcohols can be oxidised to organic acids using powerful
oxidising agents such as acidified potassium dichromate (VI)
or acidified potassium permanganate (VII) solution.
C2H5OH (l) + 2[O] ====== CH3COOH(aq) + H2O (l)
Ethanoic acid
The oxygen is from the oxidising agent. If potassium
permanganate is used, it the reaction mixture changes from
purple to colourless and if potassium dichromate is used, the
mixture changes from orange to green as the dichromate VI ion
is reduced to green chromium III ion. This forms the basis for
the breathalyzer test for drunken drivers.
4. Alcohols can undergo dehydration reactions to the
corresponding alkene using concentrated sulphuric acid
(1700C) or passing the vapour activated alumina (Al2O3)
C2H5OH (l) ========== C2H3 (g) + H2O
This reaction effectively removes water from the alcohol to
form the alkene.
5. Alcohols react with acids to form esters.
C2H5OH + CH3COOH =========== CH3COOC2H5 + H2O

Statistics
CLEMENT RADCLIFFE
Contributor
WE WILL continue the review of statistics with these.
1) Express the following scores in a Frequency Table and plot the Histogram.
22, 15, 0, 22, 11, 9, 0, 14, 20, 9, 16, 5, 11, 24,16, 5, 11, 24, 5, 5, 22 , 15, 9, 9, 11
You will notice the following:
Any value between 0 and 29 can be assigned to a class without difficulty.
Of necessity, the bars will touch.
0.5 is added and subtracted from the class intervals to obtain the class boundaries
The frequency polygon is constructed by joining the midpoint of the top of the each bar.
Using the above, please attempt the following:
The table below shows the height of orange seedlings on a farm.
SOLUTION
Since the values range from 0-24, it would be inappropriate to construct a histogram with 25 bars.
Using grouped data as follows: 0-3, 4-7, 8-11 etc, we construct the table by first doing the tally.
A. Express the above with respect to class boundaries.
B. Draw the histogram and frequency polygon to represent the data.
SOLUTION
A.
ALYSIS OF DATA
The aim is to arrive at informed decisions from the data. The following is one way in which this may be
done-:
(A) Measures of central tendency or average.
These are the values which best represent the data namely mean, median or mode.
EXAMPLE
(2) The table below shows the number of inches of rainfall which fell over a period of time.
The scores obtained by a class of ten students in a test were:
3, 3, 4, 4, 4, 6, 6, 7, 11, 12.
CALCULATE
I. The modal mark
II. The median mark
III. The mean mark
Using a scale of 2 cm to represent 5 inches on the x axis, and 1 cm to represent 1 day on the y
axis, construct the histogram to represent the data.
I. The modal mark or mode is the most frequently occurring mark. In this case, it is 4.
Answer: 4
II. The median mark is the middle value when scores are arranged in order of size. When there is an odd
number of scores; it is the single middle value. However, it is the average of the two middle scores when the
number of scores is even.
From the values given, the 5th mark is 4 and the 6th mark is 6.
The median mark is the average of the 5th (4) and 6th (6) values as there is an even number of values
(10). The median is = 4+6 = 5
2
Answer : 5
SOLUTION
Please note the following with respect to Question 2:
The table only records rainfall to the nearest whole number and this is unrealistic.
Class boundaries are recommended when the values are continuous variables.
Class Intervals are converted to class boundaries as follows:
22
SOLUTION
III. The mean mark = Sum of scores = 3+3+4+4+4+6+6+7+11+12
Number of scores
10
Mean mark = 60 = 6
10
Answer : 6
As the average is the value which best represents the group, you should be able to determine when it is
appropriate to use any of the three – the mean, the median or the mode.
