i Question Help Let a population consist of replacement, the samples have mean absolute deviations that do not center about the value of the mean absolute deviation of the indicate about a sample the values 9 cigarettes, 10 cigarettes, and 18 cigarettes smoked in a day. Show that when samples of size 2 are randomly selected with 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 Mean Absolute Deviation (9,9) (9,10) (9,18) (10,9) (10,10) (10,18) (18,9) (18,10) (18,18) Type integers or decimals rounded to one decimal place as needed)

Explanation / Answer

for mean absolute deviation =(average of all absolute deviation from mean)

hence :

( please revert if there are other part of this)

sample mean absolute deviation (9,9) 0 (9,10) 0.5 (9,18) 4.5 (10,9) 0.5 (10,10) 0 (10,18) 4 (18,9) 4.5 (18,10) 4 (18,18) 0
