Question
Suppose that you randomly selected 20 adults. Assume 18% of the population smoke. Round all
answers to 2 decimal places.
a) Using the Range Rule of Thumb (Empirical Rule), what is the minimum number of usual smokers
we can expect to get out of 20 adults?
b) Using the Range Rule of Thumb (Empirical Rule), what is the maximum number of usual smokers
we can expect to get out of 20 adults?
c) Would it be unusual to randomly select 20 smokers and get 12 smokers?
O Yes, since 12 is not between the maximum and minimum usual values.
O No, since 12 is between the maximum and minimum usual values.
