Two point estimates for \mu , X1 and X2, are found. The first estimate, X1, has E[X1] = \mu and Var[X1] = 5. The second estimate, X2, has E[X2] = \mu and Var[X2] = 7. Assume that the two estimates are independent. Part 1. What is the mean of X1 2 + X2 2 ? Part 2. What is the variation of X1 2 + X2 2 ? Part 3. What is the MSE of X1 2 + X2 2 ?
