Use the following display for the next questions. The display is based on a sample of hybrid cars, SUVs, and trucks. The dependent variable is the annual greenhouse gas emissions (in tons). The independent variables are as follows:
combination miles per gallon (Mpg), engine size in liters (ES), and number of
cylinders (Cyl).

-If exactly two independent variables are to be used to predict the annual greenhouse gas emissions, which two variables should be chosen?
