in each of the following questions, argue that both proposed estimators are consistent and asymptotically normal. Then, give their asymptotic variances and decide if one of them is always bigger than the other

As above , argue that both proposed estimators o_ and or are consistent and asymptotically normal . Then , give their asymptotic variances V ( 0 2 ) and V ( 2 ) and decide if one of them is always bigger than the other . Let * 1 . ... . In`~ ` . N ( 0 , 02 ) , for some o - > O .
