A random sample of 40 business majors who had just completed introductory courses in both statistics and accounting was asked to rate each class in terms of level of interest on a scale of 1 (very uninteresting) to 10 (very interesting). The 40 differences in the pairs of ratings were calculated and the absolute differences ranked. The smaller of the rank sums, which was for those finding accounting the more interesting, was 281. Test the null hypothesis that the population of business majors would rate these courses equally against the alternative that the statistics course is viewed as the more interesting.
