Quizplus · Accepted Answer

Since the sample correlation coefficient ranges from -1 to 1, the given options indicate a strong positive correlation. By computing the data pairs, the sample correlation coefficient between the two variables is found to be 0.9556, which is the closest to 1, indicating a very strong positive correlation. Therefore, option D is the best choice.
