6. (For stat 5504 only). Let Y = X² +XZ where X and Z are independent, normally distributed and E(Z) = E(X) = 2 and E(Z²) = E(X²) = 3, (a) if X = 1.8? Find the best (among all) predictor of Y from X. What is this value (b) Y = aX + b (find a, b). What is this value if X = 1.8? What if we only want the best linear predictor of Y from X. I.e.
