The model is an Ok fit to the data, albeit not extremely great. As our R-Square and Adjusted R-Square are as shown below:
| R square | 0.52269 |
| Adjusted R square | 0.502802 |
Our explanatory variables are jointly significant at 5% level because of the F-value and F-significance value (way below 0.05) you see below:
| df | SS | MS | F | Significance F | |
| Regression | 2 | 4.9E+08 | 2.45E+08 | 26.28179 | 1.96E-08 |
