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

  2. 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.

  3. Best Fit Line Least-Square Regression Line Y=12.63x+200.03

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

  5. 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.

  6. 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) + 200.03 = about 579 calories.

  7. 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.
