Some faculty believe that college students get less than 7 hours of sleep per night on average. A survey of 30 students found an average of 6.5 hours of sleep with a standard deviation of 1.8 hours. Are the faculty justified in their belief? Test this hypothesis at the 5% significance level. State the Null Hypothesis, Alternative Hypothesis, and the p-value for the hypothesis test. Then state your Decision (Reject H0 or Do Not Reject H0) and your Conclusion.
