Hello this is a practice problem to help me prepare for an upcoming analytics exam, I am a bit confused and this is all the information I had been provided with. Could someone give some guidance on how to do this or if something looks missing can you let me know what to ask my professor for? I am quite anxious and overwhelmed.

In this problem we focus on a vehicle table to help select the best fit model to predict a vehicle's city mileage among the four regression models provided below:

Model 1: use weight as the independent variable.

Model 2: use weight and maximum horsepower as the independent variables.

Model 3: use vehicle category as the independent variable.

Model 4: use vehicle category, weight, and maximum horsepower as the independent variables.

Answer the following questions below with the help of the JMP vehicle table provided at the bottom:

Model 1:

1. What is the RSquare for Model 1? 2. What is the Adjusted RSquare for Model 1? 3. Model 1 predicts the city mileage for a vehicle that weights 3040 lbs to be ____.

Model 2: 4. What is the RSquare for Model 2? 5. What is the Adjusted RSquare for Model 2? 6. Model 2 predicts the city mileage for a vehicle that weights 3040 lbs and has maximum horsepower of 140 to be ____.

Model 3: 7. What is The RSquare for Model 3?

8. What is the Adjusted RSquare for Model 3? 9. Model 3 predicts the city mileage for a compact vehicle to be _____.

Model 4: 10. What is the RSquare for Model 4? 11. What is the Adjusted RSquare for Model 4? 12. Model 4 predicts the city mileage for a large vehicle that weighs 3000 lbs and has a maximum horsepower of 160 to be?

T/F a. Model 4 is the best fit model (T/F) b. Model3 is the worst fit model (T/F) c. Adjusted RSquare always increases with additional independent variables (T/F) d. Adding maximum horsepower as an independent variable in Model2 explains the variations in city mileage better than that of Model1 (T/F)
