Jennings Company manufactures sophisticated electronic equipment. It hires its assembly employees on the basis of applicants' scores on standardized mathematics and spatial orientation tests. It has been shown that those who score higher on the test almost always perform better on the job. However, it has also been demonstrated that the use of the test in hiring employees has the effect of excluding African-Americans and other minority groups. Is this practice of the Jennings Company prohibited by the anti-discrimination laws? Explain.
