Math Question

Is pancakes and eggs or hot oatmeal with bacon a more filling breakfast for teenagers?
- Sixty student volunteers were randomly split into two groups and then randomly assigned their breakfast.
- One group is fed pancakes and eggs, while the other group is fed hot oatmeal and bacon.
- Each student volunteer rates his/her breakfast on a scale of 1 - 10 on how hungry they were an hour later.
If the pancake and eggs had a significantly higher average score, which of the following is true?
Pancake and eggs are more filling for the sixty volunteers.
Pancake and eggs are more filling for all teenagers.
All the aspects of experimental design were present. In general students find pancake and eggs to be more filling after an hour than hot oatmeal and bacon and we can apply this conclusion to all students.
Since the treatments were not randomly assigned the researchers can make the conclusion that pancake and eggs causes the students to be fuller longer.
