Use the formula for the joint density of Y1 and Yn shown in Exercise 8.52 and the transformation technique of Section 7.4 to find an expression for the joint density of Y1 and the sample range R = Yn – Y1. Use the result of Exercise 8.58 to show that, for the random variable P defined there, What can we conclude from this about the distribution of P when n is large?
