eness of a drug for treating insomnia in older subjects. Before treatment, 17 subjects had a mean wake time of 100.0 min. After treatment, the 17 subjects had a mean wake time of 78.3 min and a standard deviation of 20.4 min. Assume that the 17 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 100.0 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 100.0 min before the treatment? Does the drug appear to be effective? The confidence interval the mean wake time of 100.0 min before the treatment, so the means before and after the treatment This result suggests that the drug treatment significant effect. does not have has Enter your answer in each of the answer boxes.
