Commute times in the U.S. are heavily skewed to the right. We select a random sample of 61 people from the 2000 U.S. Census who reported a non-zero commute time. In this sample the mean commute time is 29.1 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. Do the hypothesis test. Use the unrounded values in Excel to find the answer for #4. 1. Find the t value. 2. This is an example of a 3. The degrees of freedom are Find the p-value- 4. 5. We should hypothesis test. the null hypothesis.
