The mean of 5.19 km from the article is inside the 95%confidence interval.No, the confidence interval does not contradict the claim. The mean of 5.19 km from the article is outside the 95%confidence interval.Yes, the confidence interval contradicts the claim. The mean of 5.19 km from the article is inside the 95%confidence interval.o Yes, the confidence interval contradicts the claim. The mean of 5.19 km from the article is outside the 95%confidence interval.X In anticipation of an upcoming election, officials in Rising Falls County are looking at the distance from each voter's home to that voter's nearest polling station.Assume that the population of all such distances for voters in Rising Falls County is approximately normally distributed. An article for the newspaper FrontlineFreedom 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 Rising Falls County voters, andfor 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 Rising Falls County live from their nearestpolling station. Then state whether the confidence interval you construct contradicts the reporter's claim. (If necessary, consult a list of formulas.)(a) Click on "Take Sample" to see the results for your random sample.Take SampleSample size:0Point estimate:0Sample standard deviation:0Critical value:0Number of peopleCompute25Enter 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 of critical values provided.)

Given that, Frontline Freedom claimed that the mean of the given population is 5.19 km. You want to…
