(population 1) or stockton steel (population 2). in particular, claude wants to go with the supplier that produces the rods with the least variability. he decides to purchase a few rods from each and have his business analyst test to determine if there is a difference in the variance of rods from the two companies. eight rods from redding produced an s12 of 0.15. a sample of 10 stockton rods resulted in an s22 of 0.04. assuming ? -0.05, test for the equality ofthe variances.
