We wish to estimate what percent of adult residents in Ventura County like chocolate. Out of 400 adult residents sampled, 277 like chocolate. Based on this, construct a 99% confidence interval for the proportion (p) of adult residents who like chocolate in Ventura County. 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.p =  ±±
