Question:

A teacher wants to see if attending study sessions results in higher grades on an exam. He takes a sample and finds that the average exam score of students attending the study sessions is 87 and the average exam score of students not attending the study sessions is 80. Each sample has an error of +/- 5. Based on this result, can one say that in the population, the students attending study sessions clearly result in higher grades?
