1 = 9. Let Y,, Yn be iid random sample from fy

1 = 9. Let Y,, Yn be iid random sample from fy (0) e-u/0,y > 0. Given that E(Y) = 0 and Var(Y) = 0. Find the MSE(mom). (Hint: There is almost no computation in this question. Just need to apply various results/formulae that we have learned to derive the answer.) Part 2: After Monday or Wednesday's lectures 10. (Continue with Q9) a. Find the fisher information of sample size n for this distribution. (Ans: 2) b. Find the Cramer-Rao lower bound for Var(), where is an unbiased estimator of 0. c. Is mom that you found in Q9 a MVUE? (You can assume the smoothness condition is satisfied.)
