3. A college professor suspects that students at his school are getting less than 8 hours of sleep a night, on average. To test his belief, the professor asks a random sample of 31 students, "How much sleep did you get last night?". His results had a mean of 7.6 hours and standard deviation of 1.52 hours. Do these data provide convincing evidence at the a = 0.01 significance level in support of the professor's suspicion? (5 points)
