Suppose X1,..., Xn, for n > 1, are sampled independently from a distribution with mean u and variance o? Consider the following four estimators for u. n n X1+ Xn 2 X1 2 n i=1 п(п + 1) i=1 a. Calculate the bias of each of these estimators. b. Calculate the standard error for each estimator. c. Which estimator would you choose to use? (Give a reason for your choice).
