Question

Refer to exercise 9 where the following data were used to investigate the relationship between the number of cars in service (1000s) and the annual revenue ($millions) for six smaller car rental companies (Auto Rental News website, August 7, 2012).


With x = cars in service (1000s) and y = annual revenue ($millions), the estimated regression equation is y = – 17.005 + 12.966. For these data SSE = 1043.03 and SST = 10,568. Do these results indicate a significant relationship between the number of cars in service and the annual revenue?
