Part 1 (It 2 idel. @ Points: 0 6 of 1' A clinical trial was conducted to test the etTectiveness of a drug for treating insomnia in older subjects. Before treatment, 24 subjects had a mean wake time of 102.0 min. After treatment. the 24 subjects had a mean wake time of 92.5 min and a standard deviation of 22.4 min. Assume that the 24 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 or 102.0 min before the treatment? Does the drug appear to be effective? Construct the 99% condence interval estimate of the mean wake time for a population with the treatment. [I min
