A clinical trial was conducted to test the effectiveness of a drug used for treating insomnia in older subjects. After treatment with the drug. 20 subjects had a mean wake time of 97.5 min and a standard deviation of 44.1 min. Assume that the 20sample 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? Find the confidence interval estimate. min<σ<min (Round to two decimal places as needed.)
