Compare the weekday and weekend/holiday hours of sleep. Each pair of numbers is from one randomly selected person. Assume that the distributions are Normal. a. Find a 95% confidence interval for the difference between means, state whether it captures 0, and explain what that shows about the means. b. Perform a hypothesis test to see whether the means are significantly different using a significance level of 0.05. Explain your conclusion clearly. Click the icon to view the data. a. Let Hdifference be the population mean difference between the weekday hours and the weekend hours (Hdifference = Hweekday - Hweekend). The 95% confidence interval is ( D. (Round to three decimal places as needed. Use ascending order.) The interval does include 0, so a hypothesis that the means are equal cannot be rejected. b. Determine the hypotheses for this test. Let µdifference be the population mean difference between the weekday hours and the weekend hours (µdifference =Hweekday - Hweekend). Choose the correct answer below. %3D A. Ho: Hdifference +0 B. Ho: Hdifference *0 Ha: Hdifference = 0 Ha: Hdifference < 0 O C. Ho: Hdifference =0 O D. Ho: Hdifference = 0 Ha: Hdifference #0 Ha: Hdifference >0 E. Ho: Hdifference O F. Ho: Hdifference = 0 Ha: Hdifference >0 Ha: Hdifference <0 Find the test statistic for this test. t= (Round to two decimal places as needed.)

What is the conclusion for this test? A. Reject Ho. The means of weekday and weekend/holiday hours of sleep are significantly different. B. Reject Ho. The means of weekday and weekend/holiday hours of sleep are not significantly different. C. Do not reject Ho. The means of weekday and weekend/holiday hours of sleep are not significantly different. D. Do not reject Ho. The means of weekday and weekend/holiday hours of sleep are significantly different.
