Suppose E(X) = 6, E(X2) = 45. E(Y) = 9, E(Y2) = 123 and Var(X+Y) = 69. Calculate the linear correlation coefficient Corr(X,Y). Enter your answer to 3 decimal places. Note: This will involve the same steps as number 3 to find Cov(X,Y) but then you must plug in that value and Var(X) and Var(Y) into the correlation equation. Note also the numbers for this problem as most likely different than those for number 3. i.e. your answer for 3 will not help you on this problem.
