HW Score: 78%, 7.8 of 10 points Part 1 of 2 & Points: 0 of 1 Save 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 98.2 min and a V standard deviation of 23.8 min. Assume that the 22 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 103.0 min before the treatment? Does the drug appear to be effective? Construct the 90% confidence interval estimate of the mean wake time for a population with the treatment. min - us min (Round to one decimal place as needed.) +
