A statistics professor finds that he can predict a student's grade on the final exam based on the number of classes the student attended over the course of the semester. What is the casual relationship between these two variables? a. Students who do well on exams are going to come to class because they enjoy the material. b. We cannot say anything definitive about the casual relationships, as all three of these explanations are possible. c. The relationship likely is the result of some third variable which accounts for both a student's attendance in class and his or her performance on the exam. d.
