11. Let X be a random variable with E(X) = 1 and var(X) = 9. Suppose I simulated X and got a value that was 2 standard deviations (of X) below what I would expect (of X). What value of X did I simulate? (a) 5 (b) 7 (c) 17 (d) 19 (e) 6 12. Suppose X and Y are random variables with joint PMF given by: Find E(X|X = Y) (a) 0.8 (b) (d) 0 (e)
