... 4. From the Empirical Rule, values more than three standard deviations away from the mean are considered extremely unlikely. Such a value would be extremely unlikely to occur if indeed H0 is true, and would give reason to reject H0. 5. Since the observed sample mean, $30,000 is so unlikely, we choos ...
