Extracted text: The problem of multicollinearity arise when the: OA. independent variables are highly correlated with the dependent variables OB. independent variables are highly correlated with one another OC. dependent variables are highly correlated with one another OD. both independent and dependent variables are highly correlated with one another To test the validity of a multiple regression model, we test the null hypothesis that the regression coefficients are all zero. We apply: OA. the F –test OB. the z –test OC. the t -test OD. either the t –test or the z –test
