Use the Massey Method with a 10 max point differential for the following system: During the Early Part of the Season: Team B beats C by 8 points. Team D beats E by 5 points. During the Middle Part of the Season: Team A beats D by 10 points. Team E beats C by 5 points. During the Later Part of the Season: Team A beats E by 4. Team E beats B by 20 points. a. Draw a directed graph of this the season. Note that this question asks you to cap the point differential. b. Write the system of equations for this season using the Massey method. c. Solve the system (using least squares) to find the ratings for each team, and use those ratings to rank them.
