We select n=2 random samples without substitution from the population 7, 10, 9, 11, 13, 12, 15 in which N=7. Find possible samples number, then draw a table which includes the information of possible samples and sample means and sample variances for each possible sample. Finally, show that  E[X] = μ and ? (2/x) = (? ^2/n) ( N−n / N
