A researcher collected a random sample of responses to a survey of university students. The researcher noted that 30% of respondents favoured classes on Fridays. a. The width of a 95% confidence interval estimate for the population proportion of students in favour of Friday classes is 0.1211. Find the sample size n. (Round the answer to the closest integer as n must be a whole number.) b. Based on your findings in part a, calculate a 99% confidence interval estimate for the population proportion of students in favour of Friday classes.

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 ±3 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. 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 population parameters. O B. 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. OC. A 99% confidence interval must be wider than an 80% confidence interval in order to be more confident that it captures the true value of…
The figure to the right shows the results of a survey in which 1018 adults from Country A, 1025 adults from Country B, 1005 adults from Country C, 999 adults from Country D, and 999 adults from Country E were asked whether national identity is strongly tied to birthplace. Construct a 95% confidence interval for the population proportion of adults who say national identity is strongly tied to birthplace for each country listed. The 95% confidence interval for the proportion of adults from Country A who say national identity is strongly tied to birthplace is (____),(____) The 95% confidence interval for the proportion of adults from Country B who say national identity is strongly tied to birthplace is (____),(____) The 95% confidence interval for the proportion of adults from Country C who say national identity is strongly tied to birthplace is (____),(____) The 95% confidence interval for the proportion of adults from Country D who say national identity is strongly tied to…
The FBI wants to determine the effectiveness of their 1010 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 283283 suspected criminals is drawn. Of these people, 9393 were captured. Using the data, construct the 85%85% confidence interval for the population proportion of people who are captured after appearing on the 1010 Most Wanted list. Round your answers to three decimal places.

You are interested in constructing a 90% confidence interval for the proportion of all caterpillars that eventually become butterflies. Of the 427 randomly selected caterpillars observed, 45 lived to become butterflies. a. Use 3 decimal places to complete the following statement: With 90% confidence the proportion of all caterpillars that lived to become a butterfly is between and . b. If many groups of 427 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.
An economist needs to estimate the proportion of residents of Sebastian that have earned a college degree. Determine the most conservative estimate of the sample size required to limit the margin of error to within 0.025 of the population proportion for a 96% confidence interval.Round the solution up to the nearest whole number.n=

Use the sample data and confidence level given below to complete parts (a) through (d). A research institute poll asked respondents if they felt vulnerable to identity theft. In the poll, n= 1004 and x = 575 who said "yes." Use a 90% confidence level. E Click the icon to view a table of z scores. .... a) Find the best point estimate of the population proportion p. (Round to three decimal places as needed.)
Two brands of tires were compared for the proportion of defective tires. Random samples of tires were collected from each brand, and the number of defective tires from each brand was recorded. The data is in the following table. Number of defective tires (x) 41 32 n Continental Michelin 320 180 a.Construct a 97% confidence interval for the difference between the two proportions. b.For part a, find the desired sample sizes if you want the Continental sample to be 1.5 times Michelin sample with a sampling error equal to 0.03. c. Conduct a test of hypothesis to determine if the defective rates are the same. Use the P-value to interpret the results (a is not given).

Compute a 90% confidence interval for the difference between the proportions of women in these two fields of engineering. Select one: O a. (0.02, 0.16) Ob. (0.01, 0.17] O. (0.04, 0.14) O d. [0.03, 0.15]
