Q.2. From the equation given in part 1 , the slope of all wheel drive denotes the partial regression coefficient of the same on mpg i.e. When the other variable namely, front remains constant unit increment in the all wheel drive will result in 0.219 unit increase in the mpg.
4. In the regression given in the R output,the slope of the rear wheel drive gives the partial regression coefficient of the same on mpg i.e. For a unit increment in the variable rear wheel drive, the mpg increases by 3.111 units, keeping all the other variables constant.
