Question 5
A clinical trial was conducted to test the effectiveness of a drug for treating insomnia in older subjects. Before treatment, 16 subjects had a mean wake time of 105.0 min. After treatment, the 16 subjects had a
mean wake time of 99.2 min and standard deviation of 23.7 min. Assume that the 16 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 105.0 min before the treatment? Does the drug appear to be effective?
