The FBI wants to determine the effectiveness of their 10 Most Wanted list. To do so, they need to find out the fraction of people who appear on the list that are actually caught. Step 2 of 2: Suppose a sample of 523 suspected criminals is drawn. Of these people, 141 were captured. Using the data, construct the 95% confidence interval for the population proportion of people who are captured after appearing on the 10 Most Wanted list. Round your answers to three decimal places.

A volunteer wearing a caveman mask was scolded by 158 out of 444 crows he encountered, and the crows scolded a person in the neutral mask in 109 out of 922 encounters.Use the percentile method to find a 90% confidence interval for the difference in the proportion of crow scoldings between volunteers wearing the caveman mask and those wearing the neutral mask. Which of the following best describes the meaning of your confidence interval? Choice 1:For 90% of crows in our sample, the difference in the rate they'll scold caveman masks and neutral masks is in our confidence interval. Choice 2:For 90% of all crows, the difference in the rate they'll scold caveman masks and neutral masks is in our confidence interval. Choice 3:We're 90% confident that the difference of the proportions of crows in our sample that scold caveman masks and neutral masks is in our confidence interval. Choice 4:We're 90% confident that the difference of the proportions of all crows that scold caveman masks and…

I need help remembering the steps for how to create a confidence interval for the following type of problem, using my TI-84 Plus calculator. Please and thank you. “A survey was taken of randomly selected Americans, age 65 and older, which found that 403 of 1002 men and 550 of 1055 women suffered from some form of arthritis. Let p1 be the sample proportion of senior women suffering from some form of arthritis, and let p2 be the sample proportion of senior men suffering from some form of arthritis. Create a 95% confidence interval for the difference in the proportions of senior men and women who have this disease, p1−p2.”
A 2013 survey of 1028 Americans had 576 respond favorably to the idea of a law that would reduce the U.S. and Russian nuclear arsenals. Produce a 99% confidence interval for the true proportion of adults in the U.S. who would respond favorably to such a law by following the steps below. Please show steps of how the answer was found. What is your point estimate? What z* (or critical value) are you using? What is the standard error of your estimate? What is the 99% confidence interval?
