Two cross country running teams participated in a (hypothetical) study in which a fraction of each team used weight training to supplement a running workout. The remaining runners did not use weight training. At the end of the season, the mean improvement in race times (in seconds) was recorded in the following table. Time improvement with weight training Gazelles - 10 seconds Time imporvement with weight training Cheetahs- 9 seconds Time improvement without weight training Gazelles- 10 seconds Time improvement without weight training Cheetahs- 1 seconds Team average time improvement Gazelles- 6.0 seconds. Team average time improvement Cheetahs- 6.2 seconds ---- Resolve the apparent inconsistency in these results by finding the percentage of each team that used weight training.
