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. f(x, y) =each front tire on a particular type of vehicle isk(x2 + y2) 21 ? x ? 30, 21 ? y ? 300 otherwise(a) compute the covariance between x and y. (round your answer to four decimal places.)cov(x, y) =(b) compute the correlation coefficient p for this x and y. (round your answer to four decimal =
