3. Two classes of statistics were taught by one instructor. Class A was evaluated using weekly team-based learning exercises, quizzes and a final exam. Class B had a midterm and final exam. Both classes were provided the same set of practice assignments. From a particular term, it was found that in Class A, 48 of 120 students attained an A- or better upon completion of the course. In Class B, 30 of 100 students attained A- or better. a) Is...
