Question

use the given confidence interval to find the margin of error and the sample proportion. (0.681,0.709) e = 0.014 (type an integer or a decimal.) \\( \hat { p } = \\) (type an integer or a decimal.)

Explanation:

Step1: Calculate the sample proportion

The sample proportion \(\hat{p}\) is the mid - point of the confidence interval.

$$ \hat{p}=\frac{0.681 + 0.709}{2} $$

$$ \hat{p}=\frac{1.39}{2}=0.695 $$

Answer:

\(\hat{p} = 0.695\)
