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 95.3 min and a standard deviation of 40.9 min. Assume that the 20 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? Question content area bottom Part 1 Find the confidence interval estimate. enter your response here min<σ
