Extracted text: In anticipation of an upcoming election, officials in Grand Ridge County are looking at the distance from each voter's horne to that voter's nearest polling station. Assume that the population of all such distances for voters in Grand Ridge County is approximately normally distributed. An artide for the newspaper Politically Sound claimed that the mean of this population is 5.19 km. You want to test this claim, so you select a random sample of 25 Grand Ridge County voters, and for each you record the distance the voter lives from their nearest polling station. Follow the steps below to construct a 95% confidence interval for the population mean of all the distances voters in Grand Ridge County live from their nearest polling station. Then state whether the confidence interval you construct contradidcts the reporter's daim. (If necessary, consult a list of formulas.) (a) Click on "Take Sample" to see the results for your random sample. Sample standard deviation Number of people Sample mean Take Sample 25 4.813 2.306 Enter the values of the sample size, the point estimate of the mean, the sample standard deviation, and the critical value you need for your 95% confidence interval. (Choose the correct critical value from the table critical values provided.) When you are done, select "Compute". Sample size: Standard error: Point estimate: Critical values Sample standard deviation: Margin of error: 0.00s -2.797 6.010 =2.492 Critical value: 0.025 -2.064 95% confidence interval: heso-1.711 Explanation Check 2021 McGraw H Education.

Extracted text: (b) Basea on your sample, graph the 95% confidence interval for the population mean of all the distances the voters in Grand Ridge County live from their nearest polling station. • Enter the values for the lower and upper limits on the graph to show your confidence interval. • For the point (), enter the claim 5.19 from the article. 95% confidence interval: 0.000 10.000 5.000 0.000 2.000 4.000 6.000 8.000 10.000 (c) Does the 95% confidence interval you constructed contradict the claim made in the article? Choose the best answer from the choices below. O No, the confidence interval does not contradict the claim. The mean of 5.19 km from the article is inside the 95% confidence interval. O No, the confidence interval does not contradict the claim. The mean of 5.19 km from the article is outside the 95% confidence interval. O Yes, the confidence interval contradicts the claim. The mean of 5.19 km from the article inside the 95% confidence interval. O Yes, the confidence interval contradicts the claim. The mean of 5.19 km from the article interval. outside the 95% confidence Explanation Check 2021 McGraw-Hill Education.
