Mercotek carried out a study to compare the productivity of its night shift with that of its day shift. Every week the company's six crews�F, G, H, R, S, and T�were ranked from first (most productive) to sixth (least productive). There were no ties. For any given week, either G and T were the two night-shift crews or else S and H were�the four other crews were the day-shift crews for that week. The following relationships held for every week of the study:
