Suppose that the population of the number of hours slept by all college students the night before finals is approximately normally distributed. A report claimed that the mean of this population is 6.25 hours. As a student wellness advocate, you want to test this claim, so you select a random sample of 16 college students and record the number of hours each slept the night before finals. Follow the steps below to construct a 95% confidence interval for the population mean of all the numbers of hours slept by college students the night before finals. Then state whether the confidence interval you construct contradicts the report's claim. (If necessary, consult a list of formulas.) (a) Click on "Take Sample" to see the results for your random sample. Take Sample Sample size: 0 Point estimate: 0 Number of students Sample standard deviation: □ 16 Sample mean 6.615 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". Standard error: Sample standard deviation Margin of error: 1.662 X S Critical values 0.005=2.947
