Like many fast-food restaurant chains, Burger King (BK) provides data on the nutrition content of its menu items on its website. Here€™s a multiple regression predicting calories for Burger King foods from Protein content (g), Total Fat (g), Carbohydrate (g), and Sodium (mg) per serving.

a) Do you think this model would do a good job of predicting calories for a new BK menu item? Why or why not?
b) The mean of Calories is 455.5 with a standard deviation of 217.5. Discuss what the value of s in the regression means about how well the model fits the data.
c) Does the R2 value of 100.0% mean that the residuals are all actually equal to zero?
