Suppose that you are estimating the unknown population mean / based on a random sample of size 3, using the following estimator: p = MIX1 + A2X2 + A3X3 Calculate the bias of your estimator if A1 = 0.2, 12 = 07, ): - 0 6, and the true population mean is u = -1. AnswerSuppose that X1,..., X,, is a random sample of size in on population X red Suppose that ux = 91 and o - 3. What is the mean of observation 17? That is what is E( X 17)? 5 a 3 @ bn c. 17 od 91Suppose that X1, ..., X, is a random sample of size n on population X Suppose that (x = 45 and of = 4 What is the variance of observation 17?
