Are the grades one receives in a course related to the amount of
time spent studying the subject? To analyze this possibility, a
student took a random sample of 60 students who had enrolled in an
accounting class last semester. She asked each student to report
his or her grade in the course and the total number of hours spent
studying accounting. The data are stored in this Excel file (SEE
