Before treatment, 18 subjects had a mean wake time of 100.0min. After treatment, the 18 subjects had a mean wake time of 75.7 min and a standard deviation of 20.4 min. Assume that the 18 sample values appear to be from anormally distributed population and construct a 95% confidence interval estimate of the mean wake time for a population with drug treatments. What does the resultsuggest about the mean wake time of 100.0 min before the treatment? Does the drug appear to be effective?Construct the 95% confidence interval estimate of the mean wake time for a population with the treatment.min<μ

To compare the dry braking distances from 30 to 0 miles per hour for two makes of automobiles, a safety engineer conducts braking tests for 35 models of Make A and 35 models of Make B. The mean braking distance for Make A is 42 feet. Assume the population standard deviation is 4.7 feet. The mean braking distance for Make B is 45 feet. Assume the population standard deviation is 4.4 feet. At a = 0.10, can the engineer support the claim that the mean braking distances are different for the two makes of automobiles? Assume the samples are random and independent, and the populations are normally distributed. Complete parts (a) rari rz (b) Find the critical value(s) and identify the rejection region(s).
