Suppose that Y1..... Y denotes an iid random sample of size 4 from an exponential distribution with mean . (a) (4 points) Let X = VYY.. Determine a multiple of X that is an unbiased estimator for 8. Hint: Don't forget about the table of common distributions on Moodle! Begin by finding the erpected value of 1. To simplify your answer as much as possible, use the fact that I(z+1) = zI(2) and (1/2) = V. (b) (2 points) Let W = VYYYY. Find a multiple of W that is an unbiased estimator for 02.
