In a random sample of five people, the mean driving distance to work was 22.5 miles and the standard deviation was 6.3 miles. Assume the population is normally distributed and use the t-distribution to find the margin of error and construct a 99% confidence interval for the population mean u. Interpret the results. Identify the margin of error. (Round to one decimal place as needed.)
