In the past, telephone solicitors for a home improvement firm have been paid an hourly wage. A small-scale experiment has been set up in which five solicitors are given further incentive in the form of 1% of the eventual sale. Data file XR14079 shows the number of sales originating from each solicitor for the day before and the day after the test policy was put into place. At the 0.05 level, has the incentive policy increased performance? Identify and interpret the p-value for the test.
