Let a population consist of the values 8 cigarettes, 9 cigarettes, and 20 cigarettes smoked in
a day. Show that when samples of size 2 are randomly selected with replacement, the
samples have mean absolute deviations that do not center about the value of the mean
absolute deviation of the population. What does this indicate about a sample mean absolute
deviation being used as an estimator of the mean absolute deviation of a population?
