urgenly need Part A and B Solution. 

Let X1,..., Xn be an independent and identically distributed Question 4 sequence of random variables from a population in {go 0 > 0}, where 1 g0(x) a. Show that E.X1 = and that the moment estimator ÔÔMOM of fo is equal to 2X. b. Show that the ML estimator ôML, of 6o is equal to X(m) = max{X1,..., X,}. c. Find the UMVU estimator of 6o by obtaining the Rao-Blackwellization of the esti- mator ÔMOM with respect to the statistic ÔML. You may use that êML is a complete and sufficient statistic for 69 and that E(X1 | X(m)) = n+1 X(n)- 2n Why is the resulting estimator unbiased? Why does it have smallest MSE out of all unbiased estimators?
