Question 8 of 21 (1 point) | Question Attempt: 1 of Unlimited Ivan Suppose that the population of heights of all fully grown male West African giraffes is approximately normally distributed. A recent article published in the Espanol Zoology Now journal daims that the mean of this population is 7.81 m. You want to test the claim made in the article, so you select a random sample of 13 fully grown male West African giraffes and record the height of each. Follow the steps below to construct a 95% confidence interval for the population mean of all heights of fully grown male West African giraffes. Then state whether the confidence interval you construct contradicts the article's claim. (If necessary, consult a list of formulas.) (a) Click on "Take Sample" to see the results for your random sample. Sample standard OO Number of giraffes Sample mean deviation Take Sample 13 5.041 1.492 M 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 of critical values provided.) When you are done, select "Compute". Sample size: X 5 Standard error: Point estimate: Critical values Sample standard deviation: Margin of error: $0.005 =3.055 0.010 = 2.681 Critical value: 2 170 Check Save For Later Submit Assignment
