Here’s the output of a regression model that regresses Calories per serving on each serving’s Protein(g), Fat(g), Fiber(g), Carbohydrate(g), and Sugars(g) content.

a) What is the regression equation?

b) To check the conditions, what plots of the data might you want to examine?

c) What does the coefficient of Fat mean in this model?
