In a survey of \(200\) youths in a town, \(12\) reported using illicit drugs. Using the normal approximation, construct a 95\% confidence interval for the true proportion of drug users among all youths in the town. The national policy states that if the prevalence exceeds \(5\%\), a special intervention must be launched. Based on the confidence interval, should the town implement the intervention?

Answer Options

A. 95\% CI: (1.85\%, 7.65\%). Since the interval does not include 5\%, the intervention should be implemented.
B. 95\% CI: (0.95\%, 4.55\%). Since the interval is entirely below 5\%, the town should not implement the intervention.
Correct Answer C. 95\% CI: (2.71\%, 9.29\%). Since the interval contains 5\%, there is insufficient evidence to trigger the intervention.
D. 95\% CI: (3.10\%, 8.90\%). Since the interval exceeds 5\% at its lower bound, the intervention is required.
Correct Answer
C
Correct Option:
95\% CI: (2.71\%, 9.29\%). Since the interval contains 5\%, there is insufficient evidence to trigger the intervention.
