(c) Consider a normal random variable X of unknown mean #x and a normal rando variable y with known mean #y. Given iid samples {(1, 1), (2, y2),..., (En, yn)} can compute the maximum likelihood estimators μx Ti, and y Σ Yi. If X and Y are not independent, show that the estimator Âx = jx +a(py – ây), is unbiased, and hence find the value of the positive constant a to minimise its variand
