We wish to estimate what percent of adult residents in a certain county are parents. Out of 100 adult residents sampled, 72 had kids. Based on this, construct a 99% confidence interval for the proportion $\displaystyle \pi$ of adult residents who are parents in this county.

Provide the point estimate and margin of error. Give your answers as decimals, to three places.

$\displaystyle \pi$ = $\displaystyle \pm$
