C2. Let X and Y be random variables, and let a and b be constants.(a) Starting from the definition of covariance, show that Cov(aX, Y): = a Cov(X, Y). You may findit helpful to remember that if EX = µx, then EaX = αμχ·(b) Show that Cov(X + b, Y) = Cov(X, Y).Now let X, Y, Z be independent random variables with common variance o².(c) Find the value of Corr(2X - 3Y + 4, 2Y – Z - 1). You may use any facts about covariance fromthe notes, including those from parts (a) and (b) of this question, provided you state them clearly.
