A clinical trial was conducted to test the effectiveness of a drug for treating insomnia in older subjects. Before treatment, 19 subjects had a mean wake time of 104.0 min. After treatmen the 19 subjects had a mean wake time of 94.4 min and a standard deviation of 20.8 min. Assume that the 19 sample values appear to be from a normally distributed population and construct a 99% confidence interval estimate of the mean wake time t a population with drug treatments. What does the result suggest about the mean wake time of 104.0 min before the treatment? Does the drug appear to be effective? B Construct the 99% confidence interval estimate of the mean wake time for a population with the treatment. min<µ
