Question
A sleep disorder specialist wants to test the effectiveness of a new drug that is reported to increase the number of hours of sleep patients get during the night. To do so, the specialist randomly selects 16 patients and records the number of hours of sleep each gets with and without the new drug. The accompanying table shows the results of the Sd ઉત two-night study. Construct a 90% confidence interval for μ, using the inequality d-t√<d<d+tc. √n the populations are normally distributed. Click the icon to view the data on hours of sleep with and without the drug. DOO Assume Calculated for each patient by subtracting the number of hours of sleep with the drug from the number without the drug. The confidence interval is hr<<hr. (Round to two decimal places as needed.)
