Question
(b): Your answer is wrong. Assume that the population lengths of adult male killer whales follow approximately a normal distribution. A recent article published in the journal Zoology Now states that the mean of this population is6.99 m. You want to test the claim in the article, so you select a random sample of 10adult male killer whales and record the lengths of each. Follow these steps to construct a confidence interval for the90%for the population mean of all lengths of adult male killer whales. Then, indicate whether the confidence interval that you construct contradicts the article's statement. (If necessary, you can refer to a list of formulas .) (to) Click "Take Sample" to see the results of your random sample. Take a sample Sample size: 10 number of killer whales Point estimate: 7241 10 sample mean 7,241 sample standard Enter the values for the sample size, point estimate of the mean, sample standard deviation, and critical value that you need to construct the confidence interval for the 90%. (Choose the correct critical value from the critical value table provided). When finished, click on "Calculate". Standard error: 0.454 deviation 1,436 X Ś
