Short Answer

Use the following data for the next five questions. Researchers studying sleep loss followed the length of sleep, in hours, of 10 individuals with insomnia before and after cognitive behavioral therapy (CBT). Assume a .05 significance level to test the claim that there is a difference between the length of sleep of individuals before
and after CBT. Also, 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.

-Construct a 95% confidence interval estimate of the mean difference between the lengths of sleep.
