Let X and Y represent concentration and viscosity of a chemical product. Suppose X and Y have a bivariate normal distribution with sX = 4, sY = 1, ÂľX = 2, and ÂľY = 1. Draw a rough contour plot of the joint probability density function for each of the following values for p:
(a) p = 0
(b) p = 0.8
(c) p = – 0.8
