clinical trial was conducted to test the effectiveness of a drug used for treating insomnia in older subjects. After treatment with the drug, 12 subjects had a mean wake time of 98.7 min and a standard deviation of 44.9 min. Assume that the 12 sample values appear to be from a normally distributed population and construct a 98\% confidence interval estimate of the standard deviation of the wake times for a population with the drug treatments. Does the result indicate whether the treatment is effective.
