2. (11 pts.) Do creative people make better teachers? Ten
teachers at a large university were given a creativity test (scores
range from 0 to 20, with higher scores indicating greater
creativity) and were evaluated regarding teaching performance by
students and peers (a score of 100 indicates an average
performance, and larger scores indicate better performance). The
creativity scores and teaching performance scores are given
