![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
95.5 min and a standard deviation of 24.5 min. Assume that the 13 sample values appear to be from a normally
distributed population and construct a 95% 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?
COD
Construct the 95% confidence interval estimate of the mean wake time for a population with the treatment.
