Let X and Y have the joint pmf defined by f(0, 0) = f(1, 2) = 0.2,

Question:

Let X and Y have the joint pmf defined by f(0, 0) = f(1, 2) = 0.2, f(0, 1) = f(1, 1) = 0.3.
(a) Compute μX, μY, σ2X, σ2Y, Cov(X, Y), and ρ.
(b) Find the equation of the least squares regression line and draw it on your graph. Does the line make sense to you intuitively?
