1. Consider another sample statistic, B. Assume that B is also an unbiased estimator of the population parameter 0. How can we use the sampling distributions of A and B to decide which is the better estimator of 0?
2. If the sample sizes on which A and B are based are large, can we apply the Central Limit Theorem and assert that the sampling distributions of A and B are approximately normal? Why or why not? (Hint: think about the requirements for the CLT.)
