A clinical trial was conducted to test the effectiveness of a drug for treating insomnia in older subjects. Before treatment, 1616 subjects had a mean wake time of 102.0102.0 min. After treatment, the 1616 subjects had a mean wake time of 97.997.9 min and a standard deviation of 23.723.7 min. Assume that the 1616 sample values appear to be from a normally distributed population and construct a 9090% 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 102.0102.0 min before the treatment? Does the drug appear to be effective? Construct the 9090% confidence interval estimate of the mean wake time for a population with the treatment.
