Question 6 of 10 0.2 Points A is a categorical variable you convert to a numerical variable by setting one category equal to 1 and the others to 0. Question 7 of 10 0.2 Points An is when the slope of one independent variable depends on the value of another independent variable. Question 8 of 10 0.2 Points is a problem when the independent variables are highly correlated with each other. Question 9 of 10 0.3 Points The value measures the amount of multicollinearity. Values above may cause problems and values above_ almost always cause problems. Question 10 of 10 0.2 Points In a multiple regression model, terms with high should be removed.Question 1 of 10 0.1 Points The interpretation of the slope is different in a multiple linear regression model as compared to a simple linear regression model. O A. True O B. False Reset Selection Question 2 of 10 0.1 Points The adjusted R2 is always smaller than the regular R2 in multiple regression model. O A. True O B. False Reset Selection Question 3 of 10 0.2 Points What is the hypothesis that the ANOVA F-test is used for a multiple regression model Y = 70 + ?1 X1+ 72 X2+ 73 X3 + O A. HO: ?1 = 72 = 73 =0, H1: At least ?i 7 0 O B. HO: At least ?i ? 0, H1: ?1 = ?1 = 72 =0 C. HO: ?1 = ?2 = 73, H1: At least ?i ? ?j O D. HO: 70 = ?1 = ?2 = ?3, H1: At least ?i ? ?j Reset Selection Question 4 of 10 0.1 Points If we have taken into account all relevant explanatory factors, the residuals from a multiple regression should be random. O A. True O B. False Reset Selection Question 5 of 10 0.1 Points Multiple regression is the process of using several independent variables to predict a number of dependent variables. O A. True O B. False Reset Selection
