Extracted text: Suppose that you randomly selected 21 adults. Assume 19% 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 21 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 21 adults? c) Would it be unusual to randomly select 21 smokers and get 18 smokers? O Yes, since 18 is not between the maximum and minimum usual values. O No, since 18 is between the maximum and minimum usual values.
