- A Clinical Trial Was Conducted To Test The Effectiveness Of A Drug For Treating Insomnia In Older Subjects Before Treat 1 (20.95 KiB) Viewed 18 times
A clinical trial was conducted to test the effectiveness of a drug for treating insomnia in older subjects. Before treatment. 22 subjects had a mean wake time of 103.0 min. After treatment, the 22 subjects had a mean wake time of 94.9 min and a standard deviation of 23.7 min. Assume that the 22 sample values appear to be from a normally distributed population and construct a 99% 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 103.0 min before the treatment? Does the drug appear to be effective? Construct the 99% confidence interval estimate of the mean wake time for a population with the treatment min<<min (Round to one decimal place as needed.)
