A) $0.476 \pm 0.044$
B) $0.476 \pm 0.088$
C) $0.432 \pm 0.088$

Question

Quizplus · Accepted Answer

The point estimate is the midpoint of the interval: $(0.432 + 0.52) / 2 = 0.476$. The margin of error is half the width of the interval: $(0.52 - 0.432) / 2 = 0.044$. Thus, the confidence interval is $0.476 \pm 0.044$.
