Assume that a sample is used to estimate a population proportion p. Find the 95% confidence interval for a sample of size 117 with 64 successes. Enter your answer as an open-interval (i.e., parentheses) using decimals (not percents) accurate to three decimal places. 95% C.I. = Answer should be obtained without any preliminary rounding. However, the critical value may be rounded to 3 decimal places.
