In 2017, the CDC administered the Youth Risk Behavior Survey (YRBS) to a random sample of 14,795 American middle and high school students. The survey asked the respondents whether they had ever been cyberbullied. 2219 people answered YES, and 12576 people answered NO. Calculate a 99% confidence interval for the proportion of the high school students who have been cyberbullied, and use these data to answer the following questions. Principal Patty claims that less than 10% of high school students have been cyberbullied. Based on your calculated confidence interval, is she correct? Yes, the calculated interval suggests that 10% (or 0.10 proportion) IS a plausible value for the parameter No, the calculated interval suggests that 10% (or 0.10 proportion) is NOT a plausible value for the parameter

You want to survey students to see what proportion of them have taken Statistics 101. This survey hasn't been previously completed, so no estimate is known. How large of a sample size is necessary if we want the margin of error to be within 4% with a 95% confidence interval?
You want to determine if the proportion of people who will vote for the president next year has increased due to current events. You take a simple random sample of 1100 individuals and find that 897 of them said that they will be voting in the election. Construct a 95% confidence interval, by hand (mean using the equations in the section). Show your work. And then write the conclusion to the confidence interval (follow the examples in the modules) in a complete sentence.
According to a poll, 86% of California adults (434 out of 506 surveyed) feel that education is one of the top issues facing California. We wish to construct a 90% confidence interval for the true proportion of California adults who feel that education is one of the top issues facing California. Find a 90% confidence interval for the population proportion. (Round your answers to three decimal places.) X * Enter a number.
Through polling, it was estimated that the percent of people who will vote for a particular candidate in an upcoming election is 36.2%. If the margin of error is 3.5, give the confidence interval for the percentage of people who will vote for the candidate in the upcoming election.% to %
A survey of 240 teachers found that two-thirds of those surveyed do not live in Sydney. Can you conclude statistically that the population proportion who do not live in Sydney is less than 0.75? Use a 95% confidence interval. What is the confidence interval and is 0.75 within the interval?
Data are used either to test a hypothesis or to construct a confidence interval, but not both. Explain.
Thelma and Louise are each attempting to estimate the proportion of adults who enjoy listening to country music. They each survey a different random sample of adults, and in each sample, the proportion who say they enjoy listening to country music is 0.29. Thelma and Louise each use their sample data to construct a confidence interval. Thelma's interval is from 0.242 to 0.338 and Louise's interval is from 0.237 to 0.323. One of these intervals was computed correctly and the other was not. Which interval must be the correct one? It's impossible to answer this question without knowing the level of confidence used for each interval. It's impossible to answer this question without knowing the sample sizes. O It's impossible to answer this question without knowing the sample sizes or the level of confidence used for each interval. Thelma's interval must be the correct interval. O Louise's interval must be the correct interval.
A sociologist is comparing the proportion of teenage boys who receive a text message at least once an hour to the percentage of teenage girls who do. She has collected data from 150 men and 150 women. Which of the following is not a condition that the sociologist should check before creating a confidence interval for the difference in population proportions?
In a survey of 1798 US adults, 1365 said they had paid a bill online within the past year. What is the LOWER endpoint of a 90% confidence interval for the population proportion? What is the UPPER endpoint of a 90% confidence interval for the population proportion?
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?
Siblings Mary and David are each attempting to estimate the proportion of families in their neighborhood who have five or more children. Mary selects a random sample of 50 families to survey, and she observes a sample proportion of 0.10. David selects a random sample of 100 families to survey, and he also observes a sample proportion of 0.10. Mary and David each use their sample data to construct a 95% confidence interval. Who will have the more narrow confidence interval? A. Both intervals will have the same width since the sample proportions are the same. B. Both intervals will have the same width since the level of confidence is the same for each interval. C. Both intervals will have the same width since the sample proportions are the same and the level of confidence is the same for each interval. D. Mary's interval will be more narrow than David's interval. E. David's interval will be more narrow than Mary's interval.
Public Policy Polling recently conducted a survey asking adults across the U.S. about music preferences. When asked, 80 of the 571 participants admitted that they have illegally downloaded music. Without performing any calculations, describe how the confidence interval would change if the confidence level changed from 99% to 90%.
