Assume that a sample is used to estimate a population proportion p. Find the 95% confidence interval for a sample of size 169 with 128 successes. Enter your answer as an open-interval (i.e., parentheses) using decimals (not percents) accurate to three decimal places. C.I.
Assume that a sample is used to estimate a population proportion p. Find the 95% confidence interval for a sample of size 155 with 20 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.
