Let x1, X2 ... Xn d n(0, 0). That is, o = q² in the usual notation and the likelihood function %%%%joint density of X1, X2, …- , Xn is as follows. L(0) = 0 > 0. exp (2x®)yn/2 Now the parameter space 2 = (0, 00). Obtain the Cramer-Rao lower bound, for unbiased estimators of e. The following "answers" have been proposed. (a) The C-R lower bound is e2(n – 1). (b) The C-R lower bound is 20²(n – 1). (c) The C-R lower bound is 202/n. (d) The C-R lower bound is o²m. (e) None of the above. The correct answer is (а) (b) (c) (d) (e) N/A (Select One)
