8. A Gallup poll asked each of 1785 randomly selected adults whether she happened to attend a house of worship in the previous seven days. Of the respondents, 750 said "yes." Give a 95% confidence interval for theproportion of all adults who claim that they attended a house of worship during the week preceding the poll.(The proportion who actually attended may be lower- some people say "yes" if they often attend, even if they didn't attend that particular week.)Determine the sample proportion pof those who answered "yes." Give your answer to 3 decimal places.

In a survey of 2318 adults, 747 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.)
You are interested in constructing a 99% confidence interval for the proportion of all caterpillars that eventually become butterflies. Of the 381 randomly selected caterpillars observed, 42 lived to become butterflies. Round answers to 4 decimal places where possible. a. With 99% confidence the proportion of all caterpillars that lived to become a butterfly is between and b. If many groups of 381 randomly selected caterpillars were observed, then a different confidence interval would be produced from each group. About percent of these confidence intervals will contain the true population proportion of caterpillars that become butterflies and about percent will not contain the true population proportion.
Students at a certain college were asked if they have a car. After surveying 1692 students, it was found that 24.8% of them have a car. The margin of error was 2.1% with a 95% confidence level. What does this margin of error tell you about the percentage of students at that college who have a car? We can be 95% confident that somewhere between ?% and ?% of the students at that college have a car.
A poll commissioned by the Center on Addiction and Substance Abuse at Columbia University found that 1,340 out of 2,000 adults interviewed believed that popular culture encourages drug use.
