Commute times in the U.S. are heavily skewed to the right

Last updated: 7/8/2022

Commute times in the U.S. are heavily skewed to the right. We select a random sample of 480 Type numbers in the boxes.people from the 2000 U.S. Census who reported a non-zero commute time. In this sample, the mean commute time is 27.7 minutes with a standard deviation of 18.5 minutes. Can we conclude from this data that the mean commute time in the U.S. is less than half an hour? Conduct a hypothesis test at the 5% level of significance. What is the p-value for this hypothesis test? (Your answer should be rounded to 4 decimal places.)
