Two efficiency experts take independent measurements Y1 and Y2 on the length of time
Chapter 6, Problem 6.94(choose chapter or problem)
Two efficiency experts take independent measurements Y1 and Y2 on the length of time workers take to complete a certain task. Each measurement is assumed to have the density function given by f (y) = $ (1/4)yey/2, y > 0, 0, elsewhere. Find the density function for the average U = (1/2)(Y1 + Y2). [Hint: Use the method of moment-generating functions.]
