Let X be Hypergeometric with parameters w, b, n. (a) Find EX 2 by thinking, without any
Chapter 4, Problem 44(choose chapter or problem)
Let X be Hypergeometric with parameters w, b, n. (a) Find EX 2 by thinking, without any complicated calculations. (b) Use (a) to find the variance of X. You should get Var(X) = N n N 1 npq, where N = w + b, p = w/N, q = 1 - p.
