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) + 200.03 = 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.
