Let X1 and X2 be random variables that are independent, both have the mean u (the mean of Xı is u and the mean of X2 is u) and known variance o? = 1. Let's %3D X, + X, 2. For u, 2 1 create an estimator û, for the mean such that û, what is a. the bias (by finding u or E( û, ))? A b. the variance (by finding o, or VAR(û, ))? C. the mean squared error?
