In general, how is a multiple linear regression model used to predict the response variable using predictor variables?

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:

Null Hypothesis (statistical notation and its description in words)

Alternative Hypothesis (statistical notation and its description in words)

Level of Significance

Report the test statistic and the P-value in a formatted table as shown below:

Table 2: Hypothesis Test for the Overall F-Test

Statistic	Value
Test Statistic	X.XX *Round off to 2 decimal places.
P-value	X.XXXX *Round off to 4 decimal places.

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 total 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?

What is the predicted total number of wins in a regular season for a team that is averaging 100 points per game with an average relative skill level of 1600?
