1 )
Assume that a sample is used to estimate a population proportion p. Find the 99% confidence interval for a sample of size 293 with 82 successes. Enter your answer as an open-interval (i.e., parentheses) using decimals (not percents) accurate to three decimal places.

99% C.I. =

Answer should be obtained without any preliminary rounding. However, the critical value may be rounded to 3 decimal places.

2)
Assume that a sample is used to estimate a population proportion p. Find the 99.9% confidence interval for a sample of size 86 with 43% 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 to 3 decimal places.

3) Assume that a sample is used to estimate a population proportion p. Find the 98% confidence interval for a sample of size 172 with 38 successes. Enter your answer as a tri-linear inequality using decimals (not percents) accurate to three decimal places.

< p <

Answer should be obtained without any preliminary rounding. However, the critical value may be rounded to 3 decimal places.
