(a) Using R package function manor'mO, simulate 100 observations from the bivariate distribution with pXY = 0.99. Using the plot() function create a scatterplot of the observations and comment on the direction and strength of the linear association. Using the function pmmomO, compute the joint probability P (X S 0, Y S 0) . (b) Do the same exercise with pXY = 0.9. (c) Do the same exercise with pXY = 0.5. (d) ) (e Do the same exercise with pXY = 0.9. Do the same exercise with pXY = 0
