The ratings are 1 (lowest quality) to 5 (highest quality) and 1 (hardest) to 5 (easiest). The numbers given are averages for each professor. Assume the trend is linear, find the correlation, and comment on what it means. Quality Easiness 4.9 3.8 4.7 3.2 4.4 3.5 4.2 2.5 3.9 1.9 3.6 2.2 Calculate the correlation. r = (Round to three decimal places as needed.) Comment on the meaning of the correlation. Choose the correct interpretation below. A. The professors that have high easiness scores tend to also have low quality scores. B. The professors that have high easiness scores tend to also have high quality scores. C. Being "easy" as a professor causes students to regard the professor as having a higher quality. D. Being "easy" as a professor causes students to regard the professor as having a lower quality.
