- 2. Research Question Do the nutritional factors in chips, such as total fat, carbohydrates and protein determine the amount of calories in chips?
- 3. Hypothesis We believe that the main nutritional factors, such as total fat, carbohydrates and protein will be directly proportional to the caloric content of the chips.
