1) Let X1, X2, X3 be a random sample of 3 units with a Normal distribution (N(H, o2 )) with expected value p and variance o2. The parameters u and o2 are unknown. Given the following estimators to estimate the parameter µ. Az = X, +X2 +X3 a) Show that the estimators are unbiased. b) Which of the unbiased estimators is more efficient? Show.
