-Express the confidence interval $0.039 < \mathrm { p } < 0.479$ in the form of $\hat { \mathrm { p } } \pm \mathrm { E }$.
A) $0.259 - 0.22$
B) $0.22 \pm 0.5$
C) $0.259 \pm 0.22$
D) $0.259 \pm 0.5$

Quizplus · Accepted Answer

The midpoint of the interval $(0.039 + 0.479) / 2 = 0.259$ is $\hat{p}$, and the margin of error $E$ is $(0.479 - 0.039) / 2 = 0.22$. Thus, the confidence interval is $0.259 \pm 0.22$.
