A dinical trial was conducted to test the ellectiveness 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 24 subjects had a mean wake time of $1.4 min and a standard deviation of 24.9 min. Assume that the 22 sample values appear to be from a normally distributed population and construct a $3% confidence interval estimate of the moun wake time for a population with drug treatments. What dont the rowill suggest about the mean wake time of 103.0 min before the treatment? Does the drug appear to be effective? Construct the $5% confidence Interval estimate of the mean wake time for a population with the treatment. min
