  1. Write simple linear regression models over the rating data frame explaining variable points in terms of variables:
    1. goals for,
    2. goals against,
    3. goals spread (goals for minus goals against).
    Find out which is the best model.
  2. Model points in terms of both goals for and goals against using multiple linear regression. Which among goals for and goals against contribute more to points? Use the answer to suggest a market strategy for a team.
