1) A clinical trial was conducted to test the effectiveness of a drug for treating insomnia in older subjects. Before treatment, 23 subjects had a mean wake time of 103.0 min. After treatment, the 23 subjects had a mean wake time of 75.6 min and a standard deviation of 23.4 min. Assume that the 23 sample values appear to be from a normally distributed population. Construct a 99% confidence interval estimate of the mean wake time for a population with...
