5. Suppose that (Y1, . . .,Yn) is a random sample

5. Suppose that (Y1, . . .,Yn) is a random sample from the uniform distribution on [6,9 + 1], where the parameter 9 varies in the set R of ail real numbers. (i) Show that 17 is a biased estimator of 9, and compute its bias. (ii) Find a simple modication of i7 which is an unbiased estimator of 9. (iii) Compute the mean squared error MSEG') made by using 17' as an estimator of 0
