Problem 6: Suppose X₁,..., X₂ are i.i.d. random variables having a N(μ, o²) distribution. Consider the estimator of o², 6 = «Σ(x − x). i=1 Recall that is the MLE if c = 1/n and is the unbiased estimator S² if c = 1/(n − 1). (a) Calculate the mean squared error of 2. (b) For which value of c is the mean squared error the smallest?
