Nutrition might also affect cognitive performance. A group of researchers hypothesize that students who eat fast food often have worse grades than those who eat healthier food. Consider the data for the two groups. The mean grades of students who regularly eat fast food is 78.5 (M1 = 78.5) and the mean grade for students who cook healthier food is 81 (M2 = 81). There were 22 participants in the study as a whole, and there are 11 participants in...
