Sue and ann decide to lose weight. sue is rich and hires a trainer. ann goes to weight watchers. sue and ann both went on diets for 2 months. they had a bet that whoever lost the most weight would have to treat the other to a mani/pedi. sue lost 15 pounds and ann lost 12. ann decided that she and sue should not compare absolute pounds lost but rather how much they lost in comparison to others in their diet group. she felt the advantage of the trainer should be factored out. for sue's trainer, her average client loses 16 pounds in 2 months with a std dev of 3 pounds. at weight watchers the average weight loss is 13 pounds with a standard deviation of 1.5 pounds. can ann win the bet?
