Problem 1. Suppose that X1,..., Xn are i.i.d. samples from N(0,02). Let X be the sample mean. • For a given 0, is it possible to find a function f of X1, ... , Xn such that E||| (X1,...,xn) - 012 <var(X)? ) (1) , • Is it possible to find a function f of X1, ..., Xn such that E[F(X1, ..., Xn)] = 0 for all 0 €1-1, 1), and (1) holds for 0 0? • Is it possible to find a function f of X1, ... , Xn such that E[f(X1, ..., Xn)] = 0 and () both hold for all 0 € (-1, 1]?
