1.State whether the following statement are True or False and also give the reason in support of your answer.
(b) If T_{1} and T_{2} are two estimators of an parameter \theta such that \operatorname{Var}\left(T_{1}\right)=1 / 2 n and \operatorname{Var}\left(T_{2}\right)=2 / n then T_{1} is more efficient than T_{2}.
