- In a recent study, 20 males used a new weight-loss supplement, and all but 4 of them experienced weight loss after two weeks. In the same study, 100 females used the same supplement, and all but 13of them experienced weight loss after two weeks. Fill in the blanks of the statement below to make the statement the most reasonable possible. The new weight-loss supplement was less effective on ? in the study because ? % of them failed to lose weight after two weeks, whereas only ?% of the ? failed to lose weight after two weeks.In a recent study, 25 males used a new weight-loss supplement, and 19 of them experienced weight loss after two weeks. In the same study, 50 females used the same supplement, and 42 of them experienced weight loss after two weeks. Fill in the blanks of the statement below to make the statement the most reasonable possible. The new weight-loss supplement was more effective on ?males/females in the study because only % of them failed to lose weight after two weeks, whereas % of the ? males/females failed to lose weight after two weeks.In a recent study, 100 males used a new weight-loss supplement, and all but 29 of them experienced weight loss after two weeks.
