possible Adinical trial was conducted to test the effectiveness of a drug for treating insomnia in older subjects. Before treatment, 13 subjects had a mean wake time of 105.0 min. After treatment, the 13 subjects had a mean wake time of 98.5 min and a standard deviation of 21.6 min. Assume that the 13 sample values appear to be from a normally distributed population and constructa 95% confidence interval estimate of the mean wake time for a population with drug treatments. What does the mult suggest about the mean wake time of 105.0 min before the treatment? Does the drug appear to be effective? Construct the B6% confidence interval estimate of the moon wake time for a population with the treatment min<<min (Round to one decimal place as needed.) What does the result suppent about the mean wake time of 105.0 min before the treatment? Does the drug appear to be effective? The confidence interval after the treatment the mean wake time of 105.0 min before the treatment, so the means before and This result suggests that the drug treatment an effect Statcrunch Next MacBook Air ese 亲 FE 20 F3 DOO FO 2 #3 $ 4 % 5 6 & 7 Q W
