Assume that a sample is used to estimate a population proportion p. Find the 99.9% confidence interval for a sample of size 353 with 27% successes. Enter your answer as an open-interval (i.e., parentheses) using decimals (not percents) accurate to three decimal places. Confidence interval =    Express the same answer as a tri-linear inequality using decimals (not percents) accurate to three decimal places. < p <    Express the same answer using the point estimate and margin of error. Give your answers as decimals, to three places.
