Q1. (a) We take n independent samples 21, 12, ..., In from the distribution: f(I) = 2.x 12 exp (- (2)7) The goal is estimating the unknown parameter). (a) Derive the maximum likelihood estimates of A in terms of the samples r1, 12, ..., In. Notice that A *0, and you would need this assumption to estimate A without too much work. (b) Suppose that n = 3, and x1 = 1.35, r2 = 2.76, x3 = 3.12. Evaluate your ML estimate A
