18. What can we say about a food item that contains 300 calories and 50 grams of carbohydrates? a. The carbohydrate content of this food item is overestimated by the model by about 42 grams. b. The carbohydrate content of this food item is predicted perfectly by the linear model. c. The carbohydrate content of this food item is underestimated by the model by about 8 grams. d. The carbohydrate content of this food item is overestimated by the model by about 8 grams. e. None of the above.

Seventy-six Starbucks food items were analyzed for the calorie and carbohydrate content. We
used linear regression to explore the relationship between the number of calories and amount
of carbohydrates (in grams) Starbucks food menu items contain. The estimated regression
equation with carbohydrates as the response variable and the calories as the explanatory
variable is ŷ = 8.94 + 0.11x, and summary statistics of the two variables is provided below.
