In a recent study, 50 males used a new weight-loss supplement, and 39 of them experienced weight loss afte
100 females used the same supplement, and 66 of them experienced weight loss after two weeks.
Fill in the blanks below to make the most reasonable statement possible.
The new weight-loss supplement was more effective on (Choose one) ▼ in the study. That is
because only % of them failed to lose weight after two weeks, whereas of the
