A 95% confidence interval using the t-distribution was calculated to be (29.4,41.6). After researching commute times to work, it was found that the population standard deviation is 9.4 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 u is (Round to two decimal places as needed.) Help me solve this View an example Get more help Clear all Check answ
