Hello, both the images are of the same question. Please help

Extracted text: Let Y,, Y, be i.i.d with mean py and variance o. Y is an unbiased estimator of uy. Is an unbiased estimator of u? First, note that for a random variable X var(X) = E(x°) - E(X? = E(x)- and E(XX) =, for itj. %3D So, in E(Y) =t j=1 j#i Hence, O A. Yes, is an unbiased estimator of u O B. No, is not an unbiased estimator of u. Y is a consistent estimator of µy. Is Y a consistent estimator of u? Click to select your answer. Type here to search 近
