Great Britain has experimented with different 40-hour work weeks to maximize production and minimize expenses. A factory tested a 5-day week (8 hour day), a 4-day week (10 hour day), and a 3 1/3 day week (12 hour day). The weekly production results follow: 8-hour day 87 76 75 90 72 10-hour day 75 82 90 80 73 12-hour day 95 76 87 82 65 Is there evidence of a difference among the mean weekly productivity levels for the three lengths of work-day?
