Question: t an define two new random variables as follows yixix2...

Question details

t an Define two new random variables as follows: Yi-Xi+X2 and Ya-x, +ax2 You are not given the constant but it is known that Cov(Yİ%) +0 Find G) The density of Y2 (ii) Cor(X2,%) (your answers shouldnt involve β) 5. Suppose X and Y are standard normal random variables Find an expres- sion for P(X -3Y S 1) in terms of the standard normal distribution function Φ in two cases: (G) X and Y are independent. (ii) X and Y have bivariate normal distribution with correlation p=1
