In a random sample of 25 people, the mean commute time to work was 31.9 minutes and the standard deviation w 7.2 minutes. Assume the population is normally distributed and use a t-distribution to construct a 99% confidence interval for the population mean μ. What is the margin of error of u? Interpret the results. *** The confidence interval for the population mean μ is . (Round to one decimal place as needed.)
