In a survey of 2261 adults, 723 say they believe in UFOs. + Construct a 99% confidence interval for the population proportion of adults who believe in UFOs. A.99% confidence interval for the population proportion is (). (Round to three decimal places as needed.) In a random sample of 25 people, the mean commute time to work was 32.5 minutes and the standard deviation was 7.3 minutes. Assume the population is normally distributed and use a t-distribution to construct a 95% confidence interval for the population mean . What is the margin of error of ? Interpret the results. The confidence interval for the population mean u is (Round to one decimal place as needed.)
