Question
In a recent study, 50 males used a new weight-loss supplement, and all but 10 of them experienced weight loss after two weeks. In the same study, 20 females used the same supplement, and all but 3 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 less effective on (Choose one) \( \boldsymbol{\nabla} \) in the study. That is because only \( \square \% \) of them lost weight after two weeks, whereas \( \square \% \) of the (Choose one) \( \boldsymbol{\text { lost weight after two weeks. }} \)

The new weight-loss supplement was less effective on **females** in the study. That is because only **85%** of them lost weight after two weeks, whereas **80%** of the **males** lost weight after two weeks. Here's how we got those numbers: Among the 20 females, 3 didn't lose weight, meaning 17 lost weight. That's 17 out of 20, which is \( (17/20) \times 100 = 85% \). For the 50 males, 10 didn’t lose weight, meaning 40 lost weight. That’s \( (40/50) \times 100 = 80% \).
