Suppose GHC wanted to understand the amount that students study for their courses. They believe the current study time is 75 minutes with a standard deviation of 10 minutes. They decide to survey students and record their study times.

They are able to survey 200 students and find the study time of 80 minutes. At the 1% level of significance, is the current study time of 75 minutes for GHC students accurate?

* This problem is a one-mean z-test because? a. The sample standard deviation is given. b. The sample mean is given c. The population standard deviation is given.

* 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 lower than alpha. b. Reject the Ho since the p-value is equal to the alpha. c. Fail to reject the Ho since the p-value is greater than alpha. * What is the conclusion based on the original claim? a. At the 1% level of significance, the average study time for GHC students is not 75 minutes. b. At the 5% level of significance, the average study time for GHC students is 27 minutes.
