A consultant is interested in the impact of the introduction of a total-quality management program on job satisfaction of employees. A random sample of 30 employees was asked to assess level of satisfaction on a scale from 1 (very dissatisfied) to 10 (very satisfied) three months before the introduction of the program. These same sample members were asked to make this assessment again 3 months after the introduction of the program. The 30 differences in the pairs of ratings were calculated and the absolute differences ranked. The smaller of the rank sums, which was for those more satisfied before the introduction of the program, was 169. What can be concluded from this finding?
