Chapter 7, Problem 36E

To determine

To analyze the association between fat and calories.

Explanation of Solution

Fast food is often considered unhealthy because much of it is high in both calories and fat. The fat and calories contents of several brands of burger are given in the question.

Now, to analyse the association between the fat and calories of the burgers of different brands, we will construct the scatterplot to discuss the same.

The scatterplot of fat and calories is as follows:

  

From the scatterplot on the above, the data do suggest a significant correlation between the number of grams of fat and the number of calories in the burgers. As the points in the scatterplot shows a pattern in the upward direction and also in a straight line. Thus, we can find an association between the calories and the fat.
