4.4-14. Let X and Y be random variables of the continu- ous type having the joint pdf f(x, y) = 8xy. 0≤x≤y≤1. Draw a graph that illustrates the domain of this pdf. (a) Find the marginal pdfs of X and Y. (b) Compute x. r. o.o, Cov(X, Y), and p. (c) Determine the equation of the least squares regression line and draw it on your graph. Does the line make sense to you intuitively?
