a) Using the Range Rule Of Thumb, what is the minimum number of usual smokers we can expect to get out of \( 20 \) adults?
b) Using the Range Rule of Thumb, 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 \( 20 \) adults and get \( 14 \) smokers?
Yes, since \( 14 \) is not between the maximum and minimum usual values.
No, since \( 14 \) is between the maximum and minimum usual values.
