Is a measure of 24 inches "far away from a mean of 15 inches? As someone with knowledge of statistics, you answer "it depends" and request the standard deviation of the underlying data. (a) Suppose the data come from a sample whose standard deviation is 3 inches. How many standard deviations is 24 inches from 15 inches? (b) Is 24 inches far away from a mean of 15 inches? (c) Suppose the standard deviation of the underlying data is 7 inches. Is 24 inches far away from a mean of 15 inches?
