The following data represent the cost of tires (in dollars) along with a variety of potential explanatory variables. Slalom time is the amount of time it took for a 3-series BMW to get through a slalom track, lap time is the amount of time it took the same car to complete a 1/3-mile lap, and stopping distance is the distance it took the BMW to stop on wet pavement traveling 60 miles per hour. Find the best regression model using each of the three techniques presented in the section. What do you notice?
