Does Nutella help concentration in class? To answer this question, we interviewed students in a grade 8 class. We started the interview by asking them how many times a week they ate Nutella and we proceeded with 20 questions relating to the material learned during the week. The results are in the table below. 

Make a scatterplot for this research question.
