Assume that a sample is used to estimate a population proportion p. Find the 99.5% confidence interval for a sample of size 318 with 63% successes. a. Enter your answer as an open-interval (i.e., parentheses) using decimals (not percents) accurate to three decimal places. Confidence interval= b. Express the same answer as a tri-linear inequality using decimals (not percents) accurate to three decimal places.
