In a random sample of 26 people, the mean commute time to work was 34.7 minutes and the standard deviation was 7.3 minutes. Assume the population is normally distributed and use a t-distribution to construct a 99% 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.) The margin of error of µ is. (Round to one decimal place as needed.) Interpret the results. .. OA.
