Assume that a sample is used to estimate a population proportion p. Find the 99.9% confidence interval for a sample of size 287 with 69 successes. Enter your answer as an open-interval (i.e., parentheses) using decimals (not percents) accurate to three decimal places. 99.9% C.I. = Answer should be obtained without any preliminary rounding. However, the critical value may be rounded

Question
**Problem Statement: Estimating Population Proportion** Assume that a sample is used to estimate a population proportion \( p \). Find the 99.9% confidence interval for a sample of size 287 with 69 successes. Enter your answer as an open interval (i.e., using parentheses) with decimals (not percents) accurate to three decimal places. \[ \text{99.9% C.I.} = \square \] *Note:* The answer should be obtained without any preliminary rounding. However, the critical value may be rounded to 3 decimal places.
