Calculate d for each patient by subtracting the number of hours of sleep with the drug from the number without the drug. The confidence interval is Construct a 90% confidence interval, using the inequality d-t.SaTo test the effectiveness of a new drug that is reported to increase the number ofhours of sleep patients get during the night, researchers randomly select 13 patients and record the number of hours of sleep each gets with and without the new drug.Patient1 2 3 4 5 678 9 10 | 11 12 13 eSleep without the drug 3.1 4.8 4.1 2.9 4.8 2.2 2.8 2.6 4.3 3.7 4.3 5.9 4.34.5 7.4 5.5 5.4 6.1 3.1 5.3 3.8 5.0 5.1 6.1 6.5 5.8Sleep using the drugCalculate d for each patient by subtracting the number of hours of sleep with the drug from the number without the drug.

Obtain the 90% confidence interval for the difference between the population mean. The 90% confidence interval for the difference between the population mean is obtained below as follows : The formula for the Confidence interval for paired differences between the mean is: The difference d for each patient is calculated below as follows: Thus, Obtain the degrees of freedom. The degrees of freedom is obtained below: Use EXCEL Procedure for finding the critical value of t. Follow the instruction to obtain the critical value of t: Open EXCEL Go to Formula bar. In formula bar enter the function as“=TINV” Enter the probability as 0.10. Enter the degrees of freedom as 12. Click enter EXCEL output: From the EXCEL output, the critical value of t at the 0.10 level of significance with the 12 degrees of freedom is 1.7823.The required confidence interval is,
