Question

An instructor has given a short quiz consisting of two parts. For a randomly selected student, let X = the number of points earned on the first part and Y = the number of points earned on the second part. Suppose that the joint pmf of X and Y is given in the accompanying table. y p(x,y) 0 5 10 15 x 0 0.03 0.06 0.02 0.10 5 0.04 0.14 0.20 0.10 10 0.01 0.15 0.14 0.01 (a) Compute the covariance for X and Y. (Round your answer to two decimal places.) Cov(X, Y) = (b) Compute ? for X and Y. (Round your answer to two decimal places.) ? =
