Consider the situation described in Example 8.4 on page
Chapter 9, Problem 8.35(choose chapter or problem)
Consider the situation described in Example 8.4 on page 234. Do these results prompt you to question the premise that \(\mu = 800\) hours? Give a probabilistic result that indicates how rare an event \(\overline{X}\ \leq\ 775\) is when \(\mu = 800\). On the other hand, how rare would it be if \(\mu\) truly were, say, 760 hours?
