Use the data in Problem 426 to find the best quadratic regression model. (There is more than one to consider.) How does this compare to the models in Problems 426 and 427?
In Problem 427, Use the data in Problem 426 to develop a multiple linear regression model. How does this compare with each of the models in Problem 426?
In Problem 426, A sample of 20 automobiles was taken, and the miles per gallon (MPG), horsepower, and total weight were recorded. Develop a linear regression model to predict MPG, using horsepower as the only independent variable. Develop another model with weight as the independent variable. Which of these two models is better?Explain.
