a. On a set of market return (x-axis)–investment return (y-axis) axes, use the data to draw the characteristic lines for investments A and B on the same graph.
b. Use the characteristic lines from part a to estimate the betas for investments A and B.
c. Use the betas found in part b to comment on the relative risks of investments A and B.
