Question

Each front tire on a particular type of vehicle is supposed to be filled to a pressure of 26 psi. Suppose the actual air pressure in each tire is a random variable-X for the right tire and Y for the left tire, with joint pdf given below. K(x2 + y2) 225 x otherwise 32, 22 y 32 f(x, y) = (a) Compute the covariance between X and Y. (Round your answer to four decimal places.) Cov(X, Y) = (b) Compute the correlation coefficient for this X and Y. (Round your answer to four decimal places.)
