We wish to estimate what percent of adult residents in a certain county are parents. Out of 300 adult residents sampled, 75 had kids. Based on this, construct a 95% confidence interval for the proportion p of adult residents who are parents in this county. Express your answer in tri-inequality form. Give your answers as decimals, to three places. Express the same answer using the point estimate and margin of error. Give your answers as decimals, to three places.

Name: Statistics 1. An investigative reporter contacts a random sample of hotels, and finds a 95% confidence interval for the proportion of hotels in the United States that have reported having bedbugs is (0.04, 0.11). a.
