The weights of Chinook salmon (the largest species of Pacific salmon) are distributed Normal(mean=44 , stdev=12). To study this distribution, we use Minitab to randomly select a sample of 100 numbers from this distribution.

For purposes of our study, we define an outlier to be any number in the sample less than 20 or greater than 68. Using the empirical rule, approximately how many outliers do we expect in this sample?

A. 5

B. 10

C. 16
