A professor went to the website RateMyProfessors.com and looked up the quality rating and also the "easiness" of the five full-time professors in one department. The ratings are 1 (lowest quality) to 5 (highest quality) and 1 (hardest) and 5 (easiest). The numbers given are average for each professor. Assume the trend is linear, find the correlation coefficient between the "quality" and "easiness". Also interpret the result: Quality (X) Easiness (Y) Zx Zy 4.8 3.8 1.1360 1.1690 4.6 3.1 0.7303 0.1711 4.3 3.4 0.1217 0.5988 3.9 2.6 -0.6897 -0.5418 3.6 2 -1.2983 -1.3972
