Question
Suppose that X, Y, and Z are jointly distributed random variables, that is, they are defined on the same sample space. Suppose that we also have the following. E (Z)=-7 E(Y)=-9 Var (X)= 32 Var (Y)=38 Var (Z)= 37 E(X)=-6 Compute the values of the expressions below. Aa E (-4X + 4) - [| 5z-4X E 4 Var (sz) + 5 = 0 E (2x) - 0
