Show that when samples of size 2 ane candomly selected with about a sample mean absolute deviation being used as an estimator of the mean absolute deviation of a population? Calouiate the mean absclute deviation for each possible sample of size 2 from the popuiation Sample Mean Absolure Deviation 11,12 1121) 12,11 12,12 12,21 21,11) 21,12) 21.21) ntegers or decimals rounded to one deoimal place as needed) Enter your answer in the edit fields and then click Chack Answer Check Ane 6Explanation / Answer
here,
MAD=(|x1-mean|+|x2-mean|)/2
thus, for (11,11), MAD=(|11-11|+|11-11|)/2=0
(11,12): MAD=(|11-11.5|+|12-11.5|)/2=0.5
(11,21):MAD=(|11-16|+|21-16|)/2=5
(12,11):MAD=(|12-11.5|+|11-11.5|)/2=0.5
(12,12):MAD=(|12-12|+|12-12|)/2=0
(12,21):MAD=(|12-16.5|+|21-16.5|)/2=4.5
(21,11):MAD=(|21-16|+|11-16|)/2=5
(21,12):MAD=(|21-16.5|+|12-16.5|)/2=4.5
(21,21):MAD=(|21-21|+|21-21|)/2=0
