The weight of male pigs ready for market is normally distributed as ~N(=300, =65). To study the random sampling of typical market pigs, we use Minitab to randomly select a sample of 169 numbers from this distribution. For purposes of this question only, we define an outlier to be any number in the sample less than 170 or greater than 430. Using the Empirical Rule, approximately how many outliers do we expect in this sample?
