The mean of 03 (X) is equal to 0. O b. The mean of 03 (X) is equal to ab. O c. Ô3(X) is a biased estimator of 0. O d. Suppose that Var (§,(X)) 62(2n–1) n2 and Varo(02(X)) 202 Then we n-1 can choose the constant a such that the mean squared error of 03 (X) is 62(2n–1) equal to n2 J e. The mean squared error (MSE) of 03 (X) is always strictly larger than the MSE of the other two estimators O f. 03(X) is an unbiased estimator of 0.
