In our Condor Cafe, the Oxnard College Culinary Program offers the most delicious and affortable breakfast and lunch choices among the 152 Community Colleges in California. This week, a random sample of 88 orders were recorded, and 57 orders were for the $5-meals. Please find the 80% confidence interval for the true proportion of the orders for the $5-meals. 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 = ±
