question 12 AND 13 please
Question 12 Commute times in the U.S. are heavily skewed to the right. We select a Type numbers in the boxes random sample of 210 people from the 2000 U.S. Census who reported a non- 10 points 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...
