TRUE or FALSE? Suppose that X1, X2,... is a stationary stochastic process with covariance function Rk = Cov(X1, X1+k), for k=0,1,... Then the variance of the sample mean can be represented as Var(X) = 1/n[Ro + 2(1-k/n)Rk] -Correct Answer TRUE TRUE or FALSE? If f(x, y) = cxy for all 0 < x < 1 and 1 < y < 2, where c is whatever value makes this thing integrate to 1, then X and Y are independent random variables. -Correct Answer TRUE. (Because f(x, y) = a(x)b(y) factors nicely, and t...
