Use the following information to answer problems 13 and 14. Cholesterol levels among 14-year-old boys have an approximately Normal distribution with mean 170 mg/dl and standard deviation 30 mg/dl. You choose a simple random sample of 4 14-year-old boys and find the average of their cholesterol levels. If you do this many times, the mean of the average cholesterol levels in mg/dl you get will be close to TAST O 170/√√4=84 O 170/4 = 42.5 O 170
