ML Estimate [10 points each] Consider n independent and identically distributed random variables X1, X2, . . . Xn (a) Let X be a Poisson random variable with unknown parameter , for all 1 i n. Find the maximum likelihood estimation of A based on X1, X2,..., Xn. (b) Let X be a Uniform random variable over [0, L] with unknown parameter L > 0, for all 1 i n. Find the maximum likelihood estimation of L based on X1, X2,..., Xn.
