1. Suppose X and Y are jointly distributed random variables with joint pdf expl= (x2 + 3xy +412 - )if 9.x2 + 4y? Si otherwise for a suitable constant c. Estimate the mean of X and obtain a 90% confidence interval for the mean 1. Suppose X and Y are jointly distributed random variables with joint pdf expl= (x2 + 3xy +412 - )if 9.x2 + 4y?
