Question

Determine the margin of error for the confidence interval for the proportion:0.554 < p <0.831

Answer 1

ANSWER:

0.1385

STEP-BY-STEP EXPLANATION:

The margin of error can be calculated as follows:

$\begin{gathered} \hat{p}=\frac{0.554+0.831}{2} \\ \hat{p}=0.6925 \\ \text{ Margin of error }=\text{ upper confidence interval - }\hat{p} \\ \text{ Margin of error }=0.831-0.6925 \\ \text{ Margin of error }=0.1385 \end{gathered}$

Therefore, the margin of error is 0.1385
