Researchers studying sleep loss followed the length of sleep, in bours, of 10 individuals with insomnia before and after cognitive behavioral therapy (CBT). The researchers hypothesize that there is a difference between the length of sleep of individuals before and after CBT. Assume the data consist of matched pairs, the samples are simple random samples, and the pairs of values are from a population having a distribution that is approximately normal Individual Before CBT Aner CBT Difference 17 6 6 a Complete the table above, filling in the difference in hours of sleep for each individual (tis: difference before CBT-afer CBT b. Identify the null and alternative hypotheses and express in symbolic form e. Is this a one-sided or a two-sided test? d. Find d of the length of sleep (tip: calculate the mean of the differences) Ted States) Accessibility: Investigate MacBook Pro LE % - 6 & 7 * 00 8 C 9 T Y U
c. Is this a one-sided or a two-sided test? d. Find d.of the length of sloep (tip: calculate the mean of the differences) e. Examining the sample data and the mean of the differences, does it appear that there is a difference in hours of sleep after CBT? £ What formula would you use to solve for the test statistic? Write out the formula only - you do not need to plug in any of the numbers.
