A clinical trial was conducted to test the effectiveness of a drug for treating insomnia in older subjects. Before treatment, 18 subjects had a mean wake time of 104.0 min. After treatment, the 18 subjects had a mean wake time of 95.4 min and a standard deviation of 24.2 min. Assume that the 18 sample values appear to be from a normally distributed population and construct a 99% 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 104.0 min before the treatment? Does the drug appear to be effective? ID Construct the 99% confidence interval estimate of the mean wake time for a population with the treatment. | min <μς min (Round to one decimal place as needed.) What does the result suggest about the mean wake time of 104.0 min before the treatment? Does the drug appear to be effective? The confidence interval the mean wake time of 104.0 min before the treatment, so the means before and after the treatment This result suggests that the drug treatment van effect.
