QuestionWhat evidence best supports the claim that more than $4\%$ of children carry a virus? Choose from the options given.

Studdy Solution
From the calculated percentages, we can see that options A, B, and C have a higher percentage (5%) of children carrying the virus than the known percentage (4%). However, option D has a lower percentage (4.2%) than the known percentage.
Therefore, the most convincing evidence to support the researcher's suspicion would be the sample with the highest percentage of children carrying the virus, which is5%. This is found in options A, B, and C. However, since option C has a much larger sample size (5,000 children), it provides the most convincing evidence.
The answer is option C Out of5,000 randomly chosen children,250 children carry the virus.
