• Let X,X,.X, be a random sample from gamma distribution, X, Gamma(2,9). The p.d.f. of X, is given by: -x/0. хе f(x,) = I(2)0² x > 0,0 > 0 a) Find a complete and sufficient statistic for 0. b) Find a minimal sufficient statistic for 0. c) Find CRLB for the variance of an unbiased estimator of 0. d) Find a UMVUE of 0. • Let X,X,.X, be a random sample from gamma distribution, X, Gamma(2,9).
