A clinical trial was conducted to test the effectiveness of a drug for treating insomnia in older subjects. Before treatment, 13 subjects had a mean wake time of 101.0 min.
After treatment, the 13 subjects had a mean wake time of 77.5 min and a standard deviation of 24.4 min. Assume that the 13 sample values appear to be from a
normally distributed population and construct a 90% confidence interval estimate of the mean wake time for a population with drug treatments. What does the result
suggest about the mean wake time of 101.0 min before the treatment? Does the drug appear to be effective?
Construct the 90% confidence interval estimate of the meno wake time for a population with the treatment.
