Transcribed Image Text:Suppose that you randomly selected 21 adults. Assume 20% of the population smoke. Round all answers to
2 decimal places.
a) Using the Range Rule of Thumb, what is the minimum number of usual smokers we can expect to get out
of 21 adults?
b) Using the Range Rule of Thumb, what is the maximum number of usual smokers we can expect to get out
of 21 adults?
c) Would it be unusual to randomly select 21 adults and get 20 smokers?
