Last time ... Commute times in the U. S. are heavily skewed to the right. We select a random sample of 500 people from the 2000 U. S. Census who reported a non-zero commute time. In this sample the mean commute time is 27.6 minutes with a standard deviation of 19.6 minutes. Are researchers able to conclude from this data that the mean commute time in the U. S. is less than half an hour?
