1. Explain how you can determine how well the model fits the data (i.e., explain the meaning of Coefficient of Determination in this Table) 2. Explain how you can test the validity of the model (i.e., explain how you will look up F-table to get the critical value of F at the significance level, 0.05 and determine the validity). 3. Explain how you can test the individual coefficients. (i.e., explain how you will look up t-table to get the critical value of t at the significance level, 0.01 and determine the statistical significance of individual variables). 4. Draw a conclusion of this model (i.e., interpret the results). Model 1 Model 1 R .760a Model 1 Regression Residual Model Summary .559 a.
