The Gallup Poll asked a random sample of 1785 adults if they attended church during the past week. Let p be the proportion ofpeople in the sample who attended church. A newspaper report claims that 40% of all U.S. adults went to church last week.Suppose this claim is true.Verify the sampling distribution of p is approximately Normal.Because np = 1785(0.40) = 714.0 ≥ 10 and n(1 − p) = 1785(0.60) = 1071 ≥ 10, the sampling distribution of p isapproximately Normal.Because 40> 30, the sampling distribution of ô is approximately Normal.Because 1785 > 30, the sampling distribution of p is approximately Normal.0.40, the distribution of p is skewed to the right.Because p =Because np = 1785(0.40) = 714.0 10 and n(1 − p) = 1785(0.60) = 1071 ≥ 10, the sampling distribution of p isnot approximately Normal.

given data n = 1785 p^ = proportion of people in the sample who attended church. p = 0.40 we have to…

18. On average, a banana will last 6.3 days from the time it is purchased in the store to the time it is too rotten to eat. Is the mean time to spoil greater if the banana is hung from the ceiling? The data show results of an experiment with 15 bananas that are hung from the ceiling. Assume that that distribution of the population is normal. 5.4, 8.2, 7.8, 6.8, 6.4, 8.3, 5, 7.5, 7, 5.3, 6.9, 8.8, 8.9, 9, 8.5 What can be concluded at the the αα = 0.05 level of significance level of significance? For this study, we should use T- Test, Z test The null and alternative hypotheses would be: H0: P or U, <>=, H1: P or U, <>=, The test statistic T,Z = (please show your answer to 3 decimal places.) The p-value = (Please show your answer to 4 decimal places.) The p-value is <> αα Based on this, we should the null hypothesis. Thus, the final conclusion is that ...

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 Politically Sound claimed that the mean of this population is 5.15 km. You want to test this claim, so you select a random sample of 23 Rising Falls County voters, and for each you record the distance the voter lives from their nearest polling station. Follow the steps below to construct a 90% confidence interval for the population mean of all the distances voters in Rising Falls County live from their nearest polling station. Then state whether the confidence interval you construct contradicts the reporter's claim. (If necessary, consult a list of formulas.)
