Countdown: Days:-o Time:-09:43:01 Question 12 Commute times in the U.S. are heavily skewed to the right. We select a random sample of 60 people from the 2000 U.S. Census who reported a non- 10 points zero commute time. In this sample the mean commute time is 28.5 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...

A group of 70 college students from a certain liberal arts college were Type numbers in the boxes. randomly sampled and asked about the number of alcoholic drinks they have 10 points in a typical week. The purpose of this study was to compare the drinking habits of the students at the college to the drinking habits of college students in general. In particular, the dean of students, who initiated this study, would like to check whether the mean number...
Commute times in the U.S. are heavily skewed to the right. We select a random sample of 200 people from the 2000 U.S. Census who reported a non-zero commute time. In this sample the mean commute time is 27.5 minutes with a standard deviation of 18.9 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...
