Looking at the "P-value" column, both Income and Size have p-values less than 0.05, indicating that they are statistically significant at the 5% level. However, School has a p-value greater than 0.05, indicating that it is not statistically significant and can be dropped from the model. Therefore, the best choice(s) are Income and Size.
