Is this possible to do using the ti-84 plus calculator? (not all calculators have the same functions) If not please use show how to using step by step with actual figures. A clinical trial was conducted to test the effectiveness of a drug for treating insomnia in older subjects. Before treatment,14 subjects had a mean wake time of 103. min. After treatment, the 14 subjects had a mean wake time of 93.5 min and a standard deviation of 21.2 min. Assume that the 14 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?
