Consider a random sample of 200 one-way commute distances (inmiles) from Radcliffe College to a student’s primary place ofresidence. The sample mean is 10.33 miles and the sample standarddeviation is 3.77 miles. What percent of students sampled livebetween 0.81 and 19.85 miles from Radcliffe College? Suppose astudent lived 25 miles from Radcliffe College. Would this commutedistance be considered an outlier?
