Extracted text: In a random sample of 25 people, the mean commute time to work was 31.6 minutes and the standard deviation was 7.1 minutes. Assume the population is normally distributed and use a t-distribution to construct a 98% confidence interval for the population mean u. What is the margin of error of u? Interpret the results. The confidence interval for the population mean u is ( D (Round to one decimal place as needed.)
