Let X be a Bernoulli Trial population with parameter 0 representing the probability of a success. Let X1,...,X, be a random sample from X and let Y = X (1- X) be an estimator for o = 0(1-0). A. Find a constant c such that cY is an unbiased estimator for o, = 0(1–0). B. Calculate the bias B(Y) C. Interpret this bias in the context of the problem.

Question 5: Definition: Let X be a population random variable and let f, (x;0) be the density function for X. Let O be an estimator for the parameter 0 based on a random sample of observations from X. 1) We define the bias of Ô by B(Ô) = E ô–0|= E E[ô]-0. 2) If E 0 = 0 then we say 0 is an unbiased estimator of 0, in which case B(0) = 0.
