Given two populations 0, 4, 8, XX and 3, 7, XX, 9. Draw possible sample of sizes (n, and n2) are two without replacement from the given populations and take mean of each sample. Develop a sampling distribution of difference between means and verify that: 2 N, - n, N, - n2 1) 2) -) = N -1 n, N, -1 Note: In the place of "XX" write last two digits of your registration number. 2.
