Suppose that you randomly selected 22 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 22 adults? b) Using the Range Rule of Thumb, what is the maximum number of usual smokers we can expect to get out of 22 adults? c) Would it be unusual to randomly select 22 adults and get 20 smokers? O No, since 20 is between the maximum and minimum usual values. Yes, since 20 is not between the maximum and minimum usual values.
