Suppose that Y₁, Y2, , Yn constitute a random sample from the density function y ≥ 0, elsewhere, f(y|0) = { 0, 2 where is an unknown, positive constant. (a) Find an estimator ₁ for by the method of moments. (b) Find an estimator Ô₂ for 0 by the method of maximum likelihood. (c) Adjust ₁ and 2 so that they are unbiased. Find the efficiency of the adjusted Â₁ relative to the adjusted 82.
