- In 2001, the polls found that 81% of American adults believed that there was a conspiracy in the death of President Kennedy. Assume a recent poll asked 1500 American adults if they believe there was a conspiracy in the assassination and it found that 1180 believe there was a conspiracy. Calculate a 91% confidence interval for the percentage of all Americans who believe in this conspiracy.A new drug to treat high cholesterol is being tested by pharmaceutical company. The cholesterol levels for 27 patients were recorded before administering the drug and after. The 99% confidence interval for the true mean difference in total cholesterol levels (after - before) was (-78.82, -31.18). Which of the following is the appropriate conclusion? Question 4 options: 1) We are 99% confident that the average difference in cholesterol levels is positive, with the higher cholesterol levels being before the drug regimen. 2) We are 99% confident that the average difference in cholesterol levels is positive, with the higher cholesterol levels being after the drug regimen. 3) We are 99% confident that the average difference in cholesterol levels is negative, with the higher cholesterol levels being before the drug regimen. 4) We are 99% confident that the average difference in…This data comes from the hours of sleep among nightshift and dayshift workers.

- The Athletics Department at a high school is interested in the difference in the run times between 11th and 12th grade students. Suppose the 11th grade students make up the first sample while the 12th grade students make up the second.Using a confidence level of 95%, the confidence interval found was (−1.8,2.9)(-1.8,2.9).Which of the following is the correct interpretation? We are 95% confident that the run times of the 11th grade students are, on average, faster than those of the 12th grade students. We are 95% confident that the run times of the 11th grade students are, on average, slower than those of the 12th grade students. We are 95% confident that the run times of the 11th grade students are, on average, about the same as those of the 12th grade students.In a sample of 580 adults, 348 had children. Construct a 95% confidence interval for the true population proportion of adults with children. Give your answers as decimals, to three placesJust B pleaseQ5. As we increase the confidence level from (e.g., 90% to 95%), the confidence interval length increases and the precision of our estimate decreases. TrueB. FalseC. UnsureSuppose that you wanted to know if the percentage of people who will attend a sporting event this year will decrease. Last year, 43% of Americans attended a sporting event. After taking a sample, you attain a sample percentage of 18% with a margin of error of 3%. Construct a confidence interval and use that interval to determine if the number of Americans who will attend a sporting event has decreased. Show your calculation for the interval and then state your conclusion in complete sentences.Here are summary statistics for randomly selected weights of newborn girls: n= 181, x = 31.8 hg, s = 7.7 hg.
