#9.
A clinical trial was conducted to test the effectiveness of a
drug for treating insomnia in older subjects. Before treatment,14
subjects had a mean wake time of 105.0min. After treatment, the 14
subjects had a mean wake time of 95.5min and a standard deviation
of 23.7min. Assume that the 14 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
of 105.0min before the treatment? Does the drug appear to be
effective?
Construct the 99% confidence interval estimate of the mean wake
time for a population with the treatment.
