Assume that population proportion is to be estimated from the sample described. Use the sample results to approximate the margin of error and \( 95 \% \) confidence interval. Sample size, \( n=505 \); sample proportion, \( \hat{p}=0.2 \) The margin of error is (Round to four decimal places as needed.)
