Question 2: Consider a random sample X1, X2, ..., Xn from a random variable X with probability density, k f(x|0) = 240 5-22/0 ө where - < x < 00, > 0 and k is a constant. (Hint: ba = paxln(b)) (a) Show that: olog(5) k= TT ( Derive the maximum likelihood estimator (MLE) for 0. ( ) Calculate Cramer-Rao Lower Bound for 0. Hint: The Cramer-Rao lower bound for a parameter 6 of a pdf f(x0) is equal to 1 n· I(0)' where I(O) = E om 5 rc-w)] [Como = a ae log[f(x|0)] (d) Is MLE a minimum variance unbiased estimator?
