Commute times in the U. S. are heavily skewed to the right. We select a random sample of 210 people from the 2000 U. S. Census who reported a non-zero commute time.
In this sample the mean commute time is 28.1 minutes with a standard deviation of 18.8 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.
