Using a single data set with no missing observations, three regressions were run

Question

Using a single data set with no missing observations, three regressions were run for dependent variable Y and independent variables X_1. X_2. and X_3. The regression models, and their associated ANOVA tables arc shown below: There are two partial F-lcsts which one would want to perform for model 2. State the hypotheses for each of these tests. Also, state w hether or not each test can be performed using the provided ANOVA tables. If a test can be performed, perform it! Perform the overall F test for model 3. There arc three partial F-tests which one would want to perform for model 3. State the hypotheses for each of these tests. For each test, state whether or not it can be performed using the provided ANOVA tables. Perform the multiple partial F test for the addition of X_1 and X_2 to a model already containing X_2.
