A clinical trial was conducted to test the effectiveness of a drug used for treating insomnia in older subjects. After treatment with the​ drug, 15 subjects had a mean wake time of 94.3 min and a standard deviation of 44.2 min. Assume that the 15 sample values appear to be from a normally distributed population and construct a ​90% 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?
