In a random sample of 2020 people, the mean commute time to work was 31.831.8 minutes and the standard deviation was 7.37.3 minutes. Assume the population is normally distributed and use a t-distribution to construct a 8080% confidence interval for the population mean muμ. What is the margin of error of muμ? Interpret the results.
