Do students perform worse when they take an exam alone than when they take an exam in a classroomsetting? Eight students were given two tests of equal difficulty. They took one test in a solitary room andthey took the other in a room filled with other students. The results are shown below.Exam ScoresAlone 73 73 87 72 74 76 85 80Classroom 78 76 93 72 81 84 83 85Assume a Normal distribution.
