A clinical trial was conducted to test the effectiveness of a drug for treating insomnia in older subjects. Before treatment, 17 subjects had a mean wake time of 103.0min .After treatment, the 17 subjects had a mean wake time of 96.9 min and a standard deviation of 24.9 min. Assume that the 17 sample value 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 treatment.What does the result suggest about the mean wake time of 103.0 min before the treatment? Does the drugs appear to be effective ? Construct the 95% confidence interval estimate of the mean wake time for a population with the treatment.
