A clinical trial was conducled to test the effectiveness of a drug for treating insomnia in older subjects Before treatment. 13 subjects had a mean wake time of 102.0 min. After treatment, the 13 subjects had a mean wake time of 98.4 min and a standard deviation of 21.9 min. Assume that the 13 sample values appear to be from a nomally distrbuted 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 1020 min before the treatment? Does the drug appear to be effective? Construct the 90% confidence interval estimate of the mean wake time for a population with the treatment. min <μ< min (Round to one decimal place as needed)
