First, let's assume that the population of sleep hours follows a normal distribution with mean 
= 8 hours (as indicated under the null hypothesis) and standard deviation 
= 1.5 hours. We want to know whether our sample mean is surprising to arise from such a population...
(h) In the first column of the table in your report, state the shape, mean, and standard deviation of this distribution of sample means (lower left graph). Also report the estimate of the p-value.
(i) Why did we count below instead of above?
