Question 1 Let yl): ef fory>0andA>1. (a) Prove E(y) = A + 1. Use integration by by parts. HintzPerhaps let a = T l A 1 (b) Suppose an estimator i for the parameter A will he the sample mean 1}. (Here, .3. = 5'). Compute the bias of the estimator :\\, that is B(:\\) (c) Propose an unbiased estimator for A. Solution to Question 1 Your answers go here. Part a: Part b: Part c
