Question

the data below show the fat and calories in fast - food hamburgers. a model was created that can estimate the number of calories in a burger when the fat content is known. complete b.

a) explain why you cannot use that model to estimate the fat content of a burger with 600 calories.
choose the correct answer below.

a. the regression model was for predicting calories from fat, not the other way around.

b. the regression model was for predicting fat from calories, not the other way around.

c. the regression model cannot extrapolate to the prediction value.

Explanation:

A regression model is built for a specific direction of prediction. Here, the model was created to estimate calories (dependent variable) from fat (independent variable). Reversing the variables (predicting fat from calories) is not what the model was designed for.

Answer:

A. The regression model was for predicting calories from fat, not the other way around.
