A health and Nutrition Examination Study has information about the average amount of hours adults sleep each night. The national average is 8 hours with a standard deviation of 2 hours. Dr. Fridgle claims that the hours of sleep are less for law students. He collects a simple random sample of 400 law students. He gets a mean of 7.9 hours per night. Is there enough evidence to support the claim that law students get less sleep?
