In Exercise 5.16, Y1 and Y2 denoted the proportions of time that employees I and II actually spent working on their assigned tasks during a workday. The joint density of Y1 and Y2 is given by
In Exercise 5.80, we derived the
5.16 Let Y1 and Y2 denote the proportions of time (out of one workday) during which employees I and II, respectively, perform their assigned tasks. The joint relative frequency behavior of Y1 and Y2 is modeled by the density
a Find P(Y1 < 1/2, Y2 > 1/4).
b Find P(Y1 + Y2 ≤ 1).
5.80 In Exercise 5.16, Y1 and Y2 denoted the proportions of time that employees I and II actually spent working on their assigned tasks during a workday. The joint density of Y1 and Y2 is given by
Employee I has a higher productivity rating than employee II and a measure of the total productivity of the pair of employees is 30Y1 + 25Y2. Find the
