In a random sample of 27 people, the mean commute time to work was 32.4 minutes and the standard deviation was 7.3 minutes. Assume the population is normally distributed and use a t-distribution to construct a 90% confidence interval for the population mean µ. What is the margin of error of µ? Interpret the results.
