A clinical trial was conducted to test the effectiveness of a drug for treating insomnia in older subjects. Before treatment, 24 subjects had a mean wake time of 103.0 min. After treatment, the 24 subjects had a mean wake time of 79.1 min and a standard deviation of 24.9 min. Assume that the 24 sample values appear to be from a normally distributed population and construct a 95% 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 103.0 min before the treatment? Does the drug appear to be effective? Construct the 95% confidence interval estimate of the mean wake time for a population with the treatment min<<min (Round to one decimal place as needed.) What does the result suggest about the mean wake time of 103 0 min before the treatment? Does the drug appear to be effective? The confidence interval the mean wake time of 103.0 min before the treatment, so the means before and after the treatment an effect This result suggests that the drug treatment
