Suppose GHC wanted to understand the commute on different campuses. They believe the current commute is greater than 28 minutes with a standard deviation of 6 minutes. They decide to survey students and record their commute times.

They are able to survey 150 students and find a commute time of 29.5 minutes. At the 5% level of significance, is the current commute time greater than 28 minutes for GHC students accurate?

* The population mean is ___ minutes.

*Choose the correct null hypothesis (Ho): a. Ho: 28 b. Ho: 28 c. Ho: = 28

*Choose the correct alternative hypothesis (Ha): a. Ho: > 28 b. Ho: < 28 c. Ho: 28

*What is the conclusion when you compare the p-value and the level of significance (alpha)? a. Reject the Ho since the p-value is equal to the alpha. b. Fail to reject the Ho since the p-value is greater than alpha. c. Reject the Ho since the p-value is lower than alpha.
