Scenario 1

Suppose UGA wanted to understand the commute on different campuses. They believe the current commute is 25 minutes with a standard deviation of 5 minutes. They decide to survey students and record their commute times. They are able to survey 50 students and find a commute time of 27 minutes. At the 5% level of significance, is the current commute time of 25 minutes for UGA students accurate?
