Question 4, 7.Z13-T Hon < Part 1 of 2 HW Score: 6.67%, 1 of 15 points @ Save O Polne: Oof 1 A clinical trial was conducted to test the effectiveness of a drug for treating insomnia in older subjects. Before treatment, 18 subjects had a mean wake time of 101.0 min. After treatment, the 18 subjects had a mean wake time of 78.3 min and a standard deviation of 24.7 min. Assume that the 18 sample values appear to be from a normally distributed population and construct a 90% 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 tie treatrnent? Does the drug appear to be effective? Construct 90% confidence interval estimate of the mean wake time for a populabon with the Yeatment min < < min (Round to one decimal place as needed.) Help me solve this Mew an example
