Exercise 2 Let X1, X2, , X\" be an iid random sample of size n from a Poisson distribution with mean A, where l :> O. [3] Find the method of moments estimator of l, i. [b] Find the maximum likelihood estimator of A, i. [0] Which of the estimators is unbiased for A? The method of moments estimator [i], the MLE [Ii], neither, or both
