Simulation
Thought Question (Think about, discuss briefly with your partner, and then move on): Explain the general process we would like to use to evaluate whether the sample mean hours we observed for our class is convincing evidence that Cal Poly students as a whole average less than 8 hour of sleep on a typical Sunday night, pretending we had collected a random sample from all Cal Poly students.

< 8):
) values are typical for random samples of this same size from a population with a mean of 8. We can do this be simulating lots and lots of random samples of 34 students from a population with a mean of 8 hours.
). We are only making a conjecture about the population mean (8).
This reasoning is pretty important. Please ask an instructor or TA if you are not clear before you continue.
