3.1 Solve the below problem = = Let Yı, Y2, and Yz be random variables, where E(Y) = 1, E(Y2) = 2, E(Y3) = -1, V(Y) = 1,V(Y2) = 3, V(Y3) = 5, ]= V Cov (Y1,Y2) = -0.4, Cov(Yı, Y3) = 1/2, and Cov(Y2, Yz) = 2. = = 3.1.1 Find the expected value and variance of U = = 2Y1 – 3Y 2 + 2Y3. (2+2=4) - 3.1.2 If W = 2Y + 2Y2, find Cov(U,W) and state if U and W are independent. (2+2=4)
