: A Clinical Trial Was Conducted To Test The Effectiveness Of A Drug For Treating Insomnia In Older Subjects Before Treat 1 (21.71 KiB) Viewed 14 times

A clinical trial was conducted to test the effectiveness of a drug for treating insomnia in older subjects. Before treatment, 19 subjects had a mean wake time of 101.0 min. After treatment, the 19 subjects had a mean wake time of 80.4 min and a standard deviation of 24.9 min. Assume that the 19 sample values appear to be from a normally distributed population and construct a 95% 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 101.0 min before the treatment? Does the drug appear to be effective? Construct the 95% confidence interval estimate of the mean wake time for a population with the treatment. min<μ< min (Round to one decimal place as needed.)
