Question

in a recent study, 50 males used a new weight - loss supplement, and 39 of them experienced weight loss after two weeks. in the same study, 25 females used the same supplement, and 17 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 select in the study. that is because % of them failed to lose weight after two weeks, whereas only % of the select failed to lose weight after two weeks.

Explanation:

Step1: Calculate male non - weight - loss rate

Number of males who didn't lose weight is $50 - 39=11$. The non - weight - loss rate for males is $\frac{11}{50}\times100\% = 22\%$.

Step2: Calculate female non - weight - loss rate

Number of females who didn't lose weight is $25 - 17 = 8$. The non - weight - loss rate for females is $\frac{8}{25}\times100\%=32\%$.

Step3: Compare the rates

Since $32\%>22\%$, the supplement was less effective on females.

Answer:

The new weight - loss supplement was less effective on females in the study. That is because 32% of them failed to lose weight after two weeks, whereas only 22% of the males failed to lose weight after two weeks.
