Problem Sets Due Before Test 1
Only turn in problems that are not bracketed. Bracketed problems are additional problems you can look
at. Round brackets indicate problems that may help you with problems that are assigned; square brackets
are additional problems on material that you should know, but you are not required to write up solutions;
curly brackets are truly optional and may contain extra nuggets that you will not be required to know but
may be interested in.
Additional assignments and deadlines will be filled in over time.

Read Chapter 1, paying careful attention to the terminology used.
Keep in mind that terminology usually exists to make distinctions.
Make a list of all the distinctions made in this chapter. (Typically
these will come in pairs. For example, male vs. female makes an
important distinction in most types of organisms.)

Note: You will notice that several of the problems in this chapter
have a sample size of n = 18. This is so you can use the table of
values on page 133 to compute your p-values. Alternatively, you
can do the simulations yourself using do() and rflip() as we did
in class. Be sure to use at least 1000 (better 10,000) repetitions.

1 Suppose you roll a standard (6-sided) die 5 times. Answer the following questions without using dbinom() or
pbinom().
(a) What is the probability that you don’t roll any sixes?
(b) What is the probability that you roll exactly one 6?
(c) What is the probability that you roll 2 or more 6s?
2 Amy was a 92% free throw shooter for the Calvin basketball
team (and a student in one of my statistics classes). You
may use dbinom() and pbinom() to answer these questions.
(a) If Amy shoots 100 shots, what is the probability that
she makes exactly 92 of them?
(b) If Amy shoots 100 shots, what is the probability that
she has a good day and makes 97 or more of them?
(c) If Amy shoots 100 shots, what is the probability that
she has a bad day and makes 85 or fewer shots?
(d) If Amy shoots 100 shots, what is the probability that
she makes between 90 and 95 (inclusive)?
