In Exercise 5.18, Y1 and Y2 denoted the lengths of life, in hundreds of hours, for components of types I and II, respectively, in an electronic system. The joint density of Y1 and Y2 is (1/8)y¡e-Oi+92)/2, yı > 0, y2 > 0, f (y1, y2) = 0, elsewhere. One way to measure the relative efficiency of the two components is to compute the ratio Y2/ Y1. Find E(Y2/Y1). [Hint: In Exercise 5.61, we proved that Y1 and Y2 are independent.]
