Problem 12E

The reading on a voltage meter connected to a test circuit is uniformly distributed over the interval (θ, θ + 1), where θ is the true but unknown voltage of the circuit. Suppose that Y1, Y2, . . . , Yn denote a random sample of such readings.

a Show that  is a biased estimator of θ and compute the bias.

b Find a function of  that is an unbiased estimator of θ .

c Find is used as an estimator of θ .
