T-Test Problem:

A professor is wondering whether allowing students to use their notes during tests improves performance. She uses one of her classes as a control group and does not allow them to use their notes, and she allows her second class to use their notes while taking their exams. Below are the grades for each 12-person class. Is there a difference in grades due to being allowed to use notes?

Control Class	Open Notes Class
78	90
72	88
76	87
74	85
60	65
90	65
55	97
72	92
87	87
86	73
73	86
62	85
