A clinical trial was conducted to test the effectiveness of a drug for treating insomnia in older subjects. Before treat
A clinical trial was conducted to test the effectiveness of a drug for treating insomnia in older subjects. Before treatment, 13 subjects had a mean wake time of 100.0 min. After treatment, the 13 subjects had a mean wake time of 77.3 min and a standard deviation of 24.2 min. Assume that the 13 sample values appear to be from a normally distributed population and construct a 90% 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 90% confidence interval estimate of the mean wake time for a population with the treatment. min<μ<min (Round to one decimal place as needed.)
