    A random sample of 85 students finds that they, on average, they get 6.5 hours of sleep a night, with a sample standard deviation of 7 hours. Would you use the z-distribution or the t-distribution to construct a confidence interval? How do you know? Construct a 95% confidence interval for the population mean. How do you interpret this interval? Is it likely that students actually get 7 hours of sleep a night? How can you tell?

Their alertness during the day is on par with that of untreated narcoleptics and those with untreated sleep apnea.
