Question

The manager of a financial planning firm is trying to train her staff to make greater use of their working time. To see whether this training is having any effect, she keeps track of monthly new business generated before and after the training, for all six staff members. The results are as shown in Exhibit 9.48 opposite. Has the manager's training resulted in increased new business? Use α = 0.025. The sample size is too small to judge normality, but you may assume that the differences are normally distributed.
