Question: 6.70 Refer to the chapter appendix in order to derive the mean of the sampling distribution of the sample variances for a sample of n

6.70 Refer to the chapter appendix in order to derive the mean of the sampling distribution of the sample variances for a sample of n observations from a population of N members when the population variance is s2. By appropriately modifying the argument regarding variances in the chapter appendix, show that E3s24 = Ns2>1N - 12 Note the intuitive plausibility of this result when n = N.
