A clinical trial was conducted to test the effectiveness of a drug for treating insomnia in older subjects. Before treatment, 17 subjects had a mean wake time of 102.0 min. After treatment, the 17 subjects had a mean wake time of 72.1 min and a standard deviation of 23.2 min. Assume that the 17 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 102.0 min before the treatment? Does the drug appear to be effective? ..... Construct the 99% confidence interval estimate of the mean wake time for a population with the treatment. min < µ < (Round to one decimal place as needed.) min What does the result suggest about the mean wake time of 102.0 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 result suggests that the drug treatment does not have an effect. Activate Windows Gato SettingsTo activate Wcrours.
