Calories vs. Fat In French Fries Emily Conger Megan Dautel Lacy Allred Jennifer Knight Bernadette Martinez

Purpose of the Study To find the relation between grams of fat and calories in a large order of french fries at 11 fast food restaurants. Hypothesis- The more grams of fat in a large order of french fries will increase the amount of calories.

Best Fit Line FriesFat (g)Calories DQ21500 Chick-fil-a23430 Artic Circle30564 Sonic18450 McDonald's25500 Wendy's25540 Burger King27540 What-a- Burger36640 Carl's Jr Jack in the Box29621 In-n-Out Burger18400 Least-Square Regression Line Y=12.63x

Residual Plot Our Information R=.902 Table II in Textbook R=.602

Analysis Our scatter plot indicates that there is a strong linear relation that exists between fat content and calories in fast-food french fries. Our residual plot demonstrates that R=0.902 is close to 1, indicating linear relationship.

Predictions To test that our hypothesis, we looked at how many calories were in 30 grams of fat. – Y=12.63(30 grams of fat) = about 579 calories.

Conclusion As a group, we have decided that the more grams of fat within fast food french fries, the calories increase substantially. From the 11 fast food restaurants we observed, we came to the conclusion that In- and-Out Burger has the lowest calories and grams of fat.
