1. consider a large population which has population mean µ, and population variance σ2. we take a sample of size n = 3 from this population, thinking of the samples as realizations of the rvs x1, x2, and x3, where the xi can be considered iid. we are interested in estimating µ. (a) consider the estimator ˆµ1 = x1 + x2− x3. is this estimator unbiased for µ? explain your answer.
