Question
We wish to estimate what percent of adult residents in a certain county are parents. Out of 600 adult residents sampled, 192 had kids. Based on this, construct a 99% 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.
< p < Express the same answer using the point estimate and margin of error. Give your answers as decimals, to three places.
p = ±±
