T D D Q Please answer the question ( x. 1 ) be bivariate normal with parameters. MX : = E ( X ) = 0 , My = E LY) = 0, 67: = Var (x) = (, Or: = Var (Y) = 1, and the correlation coefficient of ( X, Y ) is P. ") Let U = x and V = Y- pX . Find the joint poly of (V, V ). b) Find the correlation coefficient between X2 and Yz ( Hint : Use the fact that if 2 ~ N(s, 1 ), then E (24 ) = 3)
