Does the configuration of the workweek have any impact on productivity? This question is raised by a researcher who wants to compare the traditional 5-day workweek with a 4-day workweek and a workweek with three 12-hour days and one 4-hour day. The researcher conducts the experiment in a factory making small electronic parts. He selects 10 workers who spend a month working under each type of workweek configuration. The researcher randomly selects one day from each of the 3 months (three workweek configurations) for each of the 10 workers. The observed measurement is the number of parts produced per day by each worker. Use the Friedman test to determine whether there is a difference in productivity by workweekconfiguration.
