In a random sample of 28 people, the mean commute time to work was 33.1 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 μ. What is the margin of error of µ? Interpret the results. The confidence interval for the population mean μ is ( (Round to one decimal place as needed.)
