ot a population consist of the values 8 cigarettes, 9 cigarettes, and 18 cigarettes smoked in a day. Show that when samples of size 2 are randomly selected with placement, 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 bout a sample mean absolute deviation being used as an estimator of the mean absolute deviation of a population? Calculate the mean absolute deviation for each possible sample of size 2 from the population, Sample (8,8) Mean Absolute Deviation (8,9) (8,18) (9,8) (0.9) (9,18) (18,8) (18,9) (18.18) (Type integers or decimals rounded to one decimal place as needed.) Calculate the mean of the sample moan absoluto deviations. The mean of the sample mean absolute deviations is (Type an integer or decimal rounded to one decimal place an needed.) Calculate the population mean absolute deviation
