Problem 2 (Least-Squares Regression)
HL Rental Car offers rental cars in an off-airport location near a major tourist destination in Baguio. Management would like to better understand the behavior of the company's costs. One of those costs is the cost of washing cars. The company operates its own car facility in which each rental car that is returned is thoroughly cleaned before being released for rental to another customer. Management believes that the costs of operating the car wash should be related to the number of rental returns. Accordingly, the following data have been compiled:
