Question

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

Answer 1

0.1385

Explanation:

The margin of error can be calculated as follows:

`\begin{gathered} \hat{p}=(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
