The regional transit authority for a major metropolitan area wants to determine whether there is a relationship between the age of a bus and the annual maintenance cost. A sample of 10 buses is shown in the datafile AgeCost. b. Use the data to develop an estimated regression equation that could be used to predict the annual maintenance cost given the age of the bus. What is the estimated regression model? d. How much of the variation in the sample values of annual maintenance cost does the model you estimated in part (b) explain? e. What do you predict the annual maintenance cost to be for a 3.5-year-old bus?
