work2_Stat3202AU22.pdf d Homework2_Stat3202AU22.pdf (194 KB) Problem 3 Consider an unknown parameter 0. It can be estimated with either 0, with variance var(01) = ?, or, 02 with variance var(02) = 02. The estimators are correlated with Cov(01, 02) = 12, and, both 0, and 02 are unbiased. Consider the unbiased estimator 03 - a . 0, + (1 - a) . 02, where a E R. What value of a minimizes the variance of 03
