Question details

c) Consider the statistical population consisting of the tour sample variances obtained part (b), and let Y denote the random variable resulting from a simple random selectio of one number from this statistical population. Compute E(Y). (d) Compare σ3 and E(Y). If the sample variance in part (b) was computed according to formula that divides by n instead of n-1, how would ơ, and E(Y) compare? 2.
