DATAFile: Jensen Jensen Tire & Auto is deciding whether to purchase a maintenance contract for its new computer wheel alignment and balancing machine. Managers feel that maintenance expense should be related to usage, and they collected the following information on weekly usage (hours) and annual maintenance expense (in hundreds of dollars). Use the data to develop an estimated regression equation that could be used to predict the annual maintenance expense in hundreds of dollars (y) for a given number of hours of weekly usage (x). Using the estimated regression equation if the weekly usage is 35, what is the estimated annual maintenance expense in hundreds of dollars? (Round your answer to one decimal place.)
