and Confidence I In a random sample of 24 people, the mean commute time to work was 30.1 minutes and the standard deviation was 7.2 minutes. Assume the population is normally distributed and use a t-distribution to construct a 95% confidence interval for the population mean u. What is the margin of error of p? Interpret the results. The confidence interval for the population mean u is ( 27 1, 33.1 ) (Round to one decimal place as needed.) The margin of error of u is (Round to one decimal place as needed.)
