Subject: Mathematics / Statistics
Question
1. In the picture, a best subsets regression modeling of ln cost based on these four potential predictior variables is developed. The one statistic displayed in the minitab printout that shuld never be used for comparing fitted models that have different numbers of predictors is:

A: s

B: Mallows CP

C: R-Sq (adjusted)

D: R-Sq

2. From the picture, which predictor amoung the four models displayed would provide the best simple linear regression model?

A: food

B: Decore and service

C: Bang for buck

D: Type food asian

3. From the picture, which predictors amoung the four models would provide the best multiple regression model having two predictors?

A: Food with bang for buck

B: Decore and service and bang for buck

C: Bang for buck with decore and service

D: Food with decore and service

4. From the picture, which predictors amoung the four models displayed would provided the best multiple regression model having three predictors?

A: Food, decore and service, bang for buck

B:Food, bang for buck, type food asian

C:Decore and service, bang for buck, type food asian

D:Food, decore and service, type food asian

5. From the picture, amoung the 13 models shown, which variables should appear in the overall best model to use and why? Short answer two sentences:

6. Which of the predictors in the 4-predictor model was never chosen as part of any best model?

A: Food
