Let X1, X2, ..., Xn be a random sample of size n from a distribution with probability density function f(z) = Az^(A-1), 0 < z < 1, A > 0. Find the method of moments estimator of A. Calculate the estimate when X1 = 0.1, X2 = 0.2, X3 = 0.3. b) Find the maximum likelihood estimator of A. Calculate the estimate when X1 = 0.1, X2 = 0.2, X3 = 0.3.
