Does an exam score depend on the amount of time spent studying for the exam? Data was collected from a sample of eight students with summary information below: Sum(x) = 117 Sum(y) = 656 Sum(xy) = 9775 Sum(x^2) = 1869 Sum(y^2) = 54150 x-bar = 14.63 y-bar = 82 Calculate the coefficient of determination and choose the best interpretation.

Does an exam score depend on the amount of time spent studying for the exam?
