The margin of error of His ( Round to two decimal places as needed . ) A 98% confidence interval using the standard normal distribution is (` ( Round to one decimal place as needed . ) Compare the results . Choose the correct answer below . O A . The confidence interval found using the standard normal distribution is wider than the confidence interval found using the student's t-distribution . O B . The confidence interval found using the standard normal distribution has smaller lower and upper confidence interval limits . O C . The confidence interval found using the standard normal distribution is the same as the confidence interval found using the student's +-distribution . @ D. The confidence interval found using the standard normal distribution is narrower than the confidence interval found using the student 's +-distribution .In a random sample of 8 people, the mean commute time to work was 34.5 minutes and the standard deviation was 7.4 minutes. A 98% condence interval using the t-distribution was calculated to be (267,423). After researching commute times to work, it was found that the population standard deviation is 8.6 minutes. Find the margin of error and construct a 98% condence interval using the standard normal distribution with the appropriate calculations for a standard deviation that is known. Compare the results
