Suppose an environmental agency would like to investigate the relationship between the engine size of sedans, x, and the miles per gallon (MPG), y, they get. The accompanying table shows the engine size in cubic liters and rated miles per gallon for a selection of sedans. The regression line for the data is y =36.1307 - 4.0962x. Use this information to complete parts a through d. Click the icon to view the table showing engine size and MPG for 9 car models. a. Calculate the coefficient of determination.
