Simulation I
First, we are going to assume that the population hours for all students at your school follows a roughly normal distribution with mean 
= 8 hours (as indicated under the null hypothesis) and standard deviation 
= 1.5 hours (the authors' guess based on historical data, hopefully similar to what you found in your sample.) To do this, we have manufactured a large, hypothetical population of 18,000 students with these population parameter values.
