In a recent poll, 284 people were asked if they liked dogs, and 84% said they did. Find the margin of error of this poll, at the 95% confidence level. Give your answer to three decimals.
Out of 300 people sampled, 123 had kids. Based on this, construct a 95% confidence interval for the true population proportion of people with kids. Give your answers as decimals, to three places. < p <
Assume that a sample is used to estimate a population proportion p. Find the 99.5% confidence interval for a sample of size 106 with 58 successes. Enter your answer as an open-interval (i.e., parentheses) using decimals (not percents) accurate to three decimal places. 99.5% C.I. =
