/ 01 75 (14 complete) IW Score: 86.67%, 16.47 of 19 6.2.21-T Question Help In a random sample of 8 people, the mean commute time to work was 34.5 minutes and the standard deviation was 7 2 minutes. A 95% confidence interval using the t-distribution was calculated to be (28.5,40,5), After researching commute times to work, it was found that the population standard deviation is 9.5 minutes. Find the margin of error and construct a 95% confidence interval using the standard normal distribution with the appropriate calculations for a standard deviation that is known. Compare the results. The margin of error of p is 5 00 (Round to two decimal places as needed.)
