Compute the leverage values for these data, using data from all 22 car models. Which car has the largest leverage value? Find the corresponding deleted studentized residual for this car (for example, if it were the Acura NSX, your answer would be the deleted studentized residual for obs. 1). Would you consider this observation an outlier?
