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 102.0 min Adereatment, the 19 sutics had a man wake of 12.4 min and a standard deviation of 20 8 min. Assume that the 19 sample values appear to be from a nommally 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 102.0 min before the treatment? Does the drug appear to be effective? GHID Construct the 99% confidence interval estimate of the mean wake time for a population with the treatment 787 min 106 min (Round to one decimal place as needed) What does the result suggest about the mean wake time of 1020 min before the treatment? Does the drug appear to be effective? The confidence interval includes the mean wake time of 102.0 min before the treatment, so the means before and after the treatment could be the same This res gests that the affect
