Let T and T, be two unbiased estimators for an unknown parameter 6. It is given that Var(T) = 1 and Var(T2) = 3. Furthermore, T, and T2 are independent. Next, consider the estimator T3 = aT¡+ (1- a)T, where a e [0,1]. For which value of a has T3 the smallest mean squared error (MSE)? O 025 O 0.50 O 0.75 /
