Question 1

When performing hypothesis testing for multiple regression models,

A.

statisticians can only perform an F-test for the joint significance of all regressors,while the T-test can only be performed for simple regressions.

B.

statisticians can only perform a T-test for the joint significance of all regressors, while the F-test can only be performed for simple regressions.

C.

statisticians can perform an F-test to test the individual significance of eachregressor, and also can perform a T-test to test the overall significance of all regressors.

D.

statisticians can perform a T-test to test the individual significance of each regressor, and also can perform an F-test to test the overall significance of all regressors.

Question 2

A multiple regression model with 2 independent variables is estimated and the two slope coefficients are -1.04 and 2.34,This means that if both independent variables increase by 1unit at the same time, the predicted value of the dependent variable will increase by1.3.

True

False
