Question 2 Consider a population with mean µ and variance o² <∞. After collecting an ID sample of T ob- servations, you estimate the mean of the population with an estimator âr such that E(âr) = 0.5µ and V(âr) = +o². Which statement is correct? %3D A) The estimator âr is not consistent but 2ô7 is B) The estimator ây is consistent because its variance goes to zero C) We cannot determine whether the estimator ấy is consistent with this information D) The estimator 2âr is unbiased but inconsistent
