Quizplus · Accepted Answer

The fact that all students score between 75% and 80% on the final exam, regardless of their score on the first midterm, suggests that there is not a strong correlation between the scores on the two exams. If there was a strong positive correlation, we would expect to see students who did well on the first midterm also doing well on the final, and vice versa. Similarly, if there was a strong negative correlation, we would expect to see students who did poorly on the first midterm doing well on the final, and vice versa. But because all students tend to score in the same range on the final, regardless of their score on the first midterm, it suggests that the scores on the two exams are not very highly correlated. Therefore, the correct answer is C. 
Choices A and B can be ruled out because they suggest that there is a strong correlation between the two exams, which is not supported by the information given. Choice D is not a relevant response to the situation described.
