(a) fit a model with total sat score as the response and expend and takers as predictors. test the hypothesis that βexpend = βtakers = 0. do any of the two predictors have an effect on the response? (b) now add ratio to the model. test the hypothesis that βratio = 0. compare this model to the previous one using an f-test. demonstrate that the f-test and t-test here are equivalent.
