Extracted text: In a random sample of 28 people, the mean commute time to work was 31.9 minutes and the standard deviation was 7.2 minutes. Assume the population is normally distributed and use a t-distribution to construct a 98% confidence interval for the population mean u. What is the margin of error of u? Interpret the results. The confidence interval for the population mean u is ( (Round to one decimal place as needed.) The margin of error of u is (Round to one decimal place as needed.) Interpret the results. O A. If a large sample of people are taken approximately 98% of them will have commute times between the bounds of the confidence interval. O B. It can be said that 98% of people have a commute time between the bounds of the confidence interval. O C. With 98% confidence, it can be said that the commute time is between the bounds of the confidence interval. O D. With 98% confidence, it can be said that the population mean commute time is between the bounds of the confidence interval.
