A sports agency is interested in determining the average running time for distance runners to run 3 miles. For a random sample of 56 runners from a college cross country team, it is found that the average running time is 43.5 minutes with a standard deviation of 0.8 minutes. Assume that the running time for distance runners to run 3 miles is normally distributed. A 93% confidence interval for the true mean running time μ is closest to. Suppose 170 randomly selected people are surveyed to determine if they own a tablet. Of the 170 surveyed, 53 reported owning a tablet. Using a 95% confidence level, compute a confidence interval estimate for the true proportion of people who own tablets. (Give your answer to four decimal places if necessary.)
