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 parts a and 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 cannot extrapolate to the prediction value.

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

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

Explanation:

A regression model is built for a specific direction of prediction. In this case, the model was created to estimate calories (dependent variable) when fat content (independent variable) is known. Using it to estimate fat (independent variable) from calories (dependent variable) would reverse the relationship for which the model was designed.

Answer:

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