Use the MPG data to create a regression model to predict MPG from Speed and Displacement: MPG

Question:

Use the MPG data to create a regression model to predict MPG from Speed and Displacement: MPG = β0 + β1( Speed) + β2( Displacement).
a. What are the regression equation and R2 value?
b. Look at residual versus Speed and residual versus Displacement plots. Describe any patterns you see.
c. What does the residual normal probability plot show?
