This Test: 164 pts possible see 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 101.0 min. After treatment, the 22 subjects had a mean wake time of 72.5 min and a standard deviation of 20.5 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.

Construct the 99% confidence interval estimate of the mean wake time for a population with the treatment. see s min
