Problem
C Denoteone sineticics In a study of pain relievers, 100 people were given product A, and all but 27 experienced relief. In the same study, 20 people were given product $B$, and all but 4 experienced relief Fill in the blanks below to make the most reasonable statement possible. Product (Choose one) 7 performed worse in the study. That is because $] \%$ failed to got relief with this product, whereas only 096 falled to get relief with Product (Choose one) $\mathbf{v}$
Solution
Step 1 ：Calculate the percentage of people who failed to get relief with Product A: \( \frac{27}{100} \times 100 = 27\% \)
Step 2 ：Calculate the percentage of people who failed to get relief with Product B: \( \frac{4}{20} \times 100 = 20\% \)
Step 3 ：Compare the percentages to determine which product performed worse: \( 27\% > 20\% \)
Step 4 ：Final Answer: Product \( \boxed{A} \) performed worse in the study. That is because \( 27\% \) failed to get relief with this product, whereas only \( 20\% \) failed to get relief with Product \( \boxed{B} \)
