A professor went to a website for rating professors and looked up the quality rating and also the "easiness" of the six full-time professors in one
department. 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.
Calculate the correlation.
r = (Round to three decimal places as needed.)
