Question

A) Assume that a sample is used to estimate a population proportion p. Find the 90% confidence interval for a sample of size 246 with 64% successes. Enter your answer as an open-interval (i.e., parentheses) using decimals (not percents) accurate to three decimal places.

C.I. =

B) Assume that a sample is used to estimate a population proportion p. Find the 95% confidence interval for a sample of size 160 with 62% successes. Enter your answer as an open-interval (i.e., parentheses) using decimals (not percents) accurate to three decimal places.

C)

Assume that a sample is used to estimate a population proportion p. Find the 98% confidence interval for a sample of size 195 with 103 successes. Enter your answer as a tri-linear inequality using decimals (not percents) accurate to three decimal places.

< p <

D)
