  • What is the equation for your model?
  • What are the results of the overall F-test? Summarize all important steps of this hypothesis test. This includes:
  1. Null Hypothesis (statistical notation and its description in words)
  2. Alternative Hypothesis (statistical notation and its description in words)
  3. Level of Significance
  4. Report the test statistic and the P-value in a formatted table as shown below:

Test Statistic

X.XX

*Round off to 2 decimal places.

P-value

X.XXXX

*Round off to 4 decimal places.

  1. Conclusion of the hypothesis test and its interpretation based on the P-value
  • Based on the results of the overall F-test, is at least one of the predictors statistically significant in predicting the number of wins in the season?
  • What are the results of individual t-tests for the parameters of each predictor variable?

Is each of the predictor variables statistically significant based on its P-value? Use a 1% level of significance.

  • Report and interpret the coefficient of determination.
  • What is the predicted total number of wins in a regular season for a team that is averaging 75 points per game with a relative skill level of 1350 and average point differential of -5?
  • What is the predicted total number of wins in a regular season for a team that is averaging 100 points per game with a relative skill level of 1600 and average point differential of +5?
