A magazine provided results from a poll of 500 adults who were asked to identify their favorite pie. Among the 500 respondents, 11% chose chocolate pie, and themargin of error was given as +4 percentage points. Given specific sample data, which confidence interval is wider the 90% confidence interval or the 80%confidence interval? Why is it wider?Choose the correct answer belowOA. A 90% confidence interval must be wider than an 80% confidence interval in order to be more confident that it captures the true value of the populationproportionOB. A 90% confidence interval must be wider than an 80% confidence interval because it contains 90% of the true population parameters, while the 80%confidence interval only contains 80% of the true population parametersOC. An 80% confidence interval must be wider than a 90% confidence interval in order to be more confident that it captures the true value of the populationproportion.OD. An 80% confidence interval must be wider than a 90% confidence interval because it contains 100% -80% - 20% of the true population parameters, whilethe 90% confidence interval only contains 100%-90% = 10% of the true population parameters

A magazine provided results from a poll of 1500 adults who were asked to identify their favorite pie. Among the 1500 respondents, 13% chose chocolate pie, and the margin of error was given as +3 percentage points. What values do p, q, n, E, and p represent? If the confidence level is 95%, what is the value of a? The value of p is The value of a is The value of n is The value of E is The value of p is
A new fertilizer was applied to the soil of 276 bean plants. 24% showed increased growth. Find the margin of error and 95% confidence interval for the percentage of all bean plants which show increased growth after application of the fertilizer. Round all answers to 2 decimal places. Margin of Error (as a percentage): Confidence Interval: % to
A college professor would like to estimate the proportion of students who pull an "all-nighter," meaning they study all night for an upcoming exam. She selects a random sample of 100 students from her large college and finds that the 99% confidence interval for the true proportion of students who pull an all-nighter is 0.48 to 0.62. Which of these statements is a correct interpretation of the confidence level? O Approximately 99% of all students have pulled an all-nighter. O There is a 99% probability that the true proportion of all students who pull an all-nighter is between 0.48 and 0.62. If many random samples of size 100 are selected from all students at this college, approximately 99% of the intervals would capture the true proportion who pull an all-nighter. C Approximately 99% of the sample proportions of students who pull an all-nighter, based on random samples of size 100 from the population of all students at this college, will fall between 0.48 and 0.62.
Vlad the Impaler promotes many of his soldiers into generals (don't ask what happened to the past generals). Haley thinks the proportion is about 79%, but wants to estimate the proportion better by sampling soldiers until her margin of error for a 93% Confidence Interval is less than 0.005. How many soldiers should Haley sample?
A poll was conducted to determine why Americans decide not to go to college. Of the 335 Americans who didn't go to college survey surveyed, 47% decided not to go to college because they couldn't afford it. Suppose we wanted the margin of error for the 90% confidence level to be about 1.5%. What sample size would you recommend for the survey? Round your answer appropriately.
If two people used the same data and one person made a 90% confidence interval and the other person made a 95% confidence interval for p, which interval would be more narrow? is it; a. The 90% Confidence interval b. The 95% Confidence interval c. We cannot tell from the information alone.
Debbie and Ethan are going to construct confidence intervals from the same simple random sample. Debbie's confidence interval will have a 98% confidence interval and Ethan's will have a 95% confidence interval. A. Which confidence interval, if there is a difference will have a larger margin of error? B. Which confidence interval is more likely to cover the population mean, if there is a difference I am using a Ti84 and need to know how to get the answer.
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 871 suspected criminals is drawn. Of these people, 243 were captured. Using the data, construct the 99%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.

Round your answers to three decimal places.) , (c) What is the 95% confidence interval? (Use a table or SALT. Round your answers to three decimal places.) , (d) Which interval is wider, the 90% confidence interval or the 95% confidence interval? 90% confidence interval 95% confidence interval
A statistics student wants to conduct a study to determine the proportion of workers in Cititon who commute to another town for work. If the student wants a 90% confidence interval with a margin of error of 2%, how many workers should be in her sample?
Days before a presidential election, an article based on a nationwide random sample of registered voters reported the following statistic, "52% (±3%) of registered voters will vote for Robert Smith." What is the "±3%" called? The "±3%" is called the confidence interval for a proportion. margin of error. sample proportion. standard error.
A magazine provided results from a poll of 500 adults who were asked to identify their favorite pie. Among the 500 respondents, 11% chose chocolate pie, and the margin of error was given as ±5 percentage points. Given specific sample data, which confidence interval is wider: the 99% confidence interval or the 80% confidence interval? Why is it wider? Choose the correct answer below. O A. An 80% confidence interval must be wider than a 99% confidence interval because it contains 100% - 80% = 20% of the true population parameters, while the 99% confidence interval only contains 100% -99% = 1% of the true population parameters. B. An 80% confidence interval must be wider than a 99% confidence interval in order to be more confident that it captures the true value of the population proportion. O C. A 99% confidence interval must be wider than an 80% confidence interval because it contains 99% of the true population parameters, while the 80% confidence interval only contains 80% of the true…
