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)y₁e-(v₁+y₂)/2, y₁ > 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.]
