Draw all possible random samples of size n, =2 without replacement from the finite population consisting of -3. XX, and +3. Similarly draw all possible random samples of size n, = 2 with replacement, from the population -1, 0, XX, and +1. a. Find the possible difference between the sample means of the two populations and construct the sampling distribution of (X, - 12) b. Verify that /(2,-17) = #1 - #2. N1-n1 C. And verify that O'(2,-12) + N1-1 n2 Note: In the place of "XX" write last two digits of your registration number
