Q1. The reading on a voltage meter connected to a test circuit is uniformly distributed over the interval (6, 6 + 1), Where 6 is the true but unknown voltage of the circuit. Suppose that Y1, Y2, - - - ,Yn denote a random sample of such readings. (a) Show that Y is a biased estimator of 6 and compute the bias. (b) Find a function of 17 that is an unbiased estimator of (9. (c) Find MSE(l_/) when l7 is used as an estimator of 9
