Let X denote the student marks in a statistics course and Y the student marks in a math course. Let X and Y have a bivariate normal distribution with parameters Hy = 70, 0x2 = 100, Hy = 80, oy2 = 169, and p = 5/13. Find the following: a. E(YTX=75) (Round to two places of decimal) b. Var ( YTX =75) (Round to four places of decimal) c. P ( 70 <Y < 80 1 X = 75)
