Given data in the file P2_13.XLS from a recent survey of chief executive officers from 350 of the nation’s biggest businesses (The Wall Street Journal, April 9, 1998), choose a simple random sample of 25 executives and find the mean, median, and standard deviation of the bonuses awarded to them in 1997. How do these sample statistics compare to the mean, median, and standard deviation of the bonuses given to all executives included in the frame?
