Enter the average exam grade of students who studied, followed by the average exam grade of the students who did not study, using two significant figures, separated by a comma. After the exam has been completed, you have the students anonymously fill out a questionnaire asking about their study habits for the exam and the grade they earned on the exam. From the surveys, you randomly select 10 students who studied for the exam and 10 students who did not study for the exam. You create the table showing the students' exam grades given here: Grades of 10 students who studied Exam grade 94 96 90 88 89 100 77 96 97 93 Grades of 10 students who did not study Exam grade 65 72 71 64 55 49 88 66 76 44
