A) $3.50 \% < p < 6.90 \%$
B) $3.77 \% < p < 6.63 \%$
C) $2.96 \% < p < 7.44 \%$
D) $3.18 \% < p < 7.22 \%$

Quizplus · Accepted Answer

The sample proportion is 34/654. Using the standard formula for a confidence interval for a proportion and a 98% confidence level, the interval is calculated to be approximately $3.18 \% < p < 7.22 \%$.
