Let Y,., Y, be i.i.d with mean py and variance o Y is an unbiased estimator ofuy. Is Y an unbiased estimator of p? First, note that for a random variable X var(X) = E(X) - E(X? =E(x)-, and E(XX) =r, for itj. So, = E i= 1 j=1 j#i Hence, O A. is an unbiased estimator of u Yes, O B. No, Ý 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. e Type here to search
