In the chi-square test, the whites were assumed to stay in occupationof specific jobs such as technical jobs, professional jobs andadministrative. The Africans were assumed to have a downward mobileto craftsman occupation, farm, labor, and equipment operativetransport.
Thenull hypothesis for t-test was positive. Technology advancement hadre-shuffled the existing structure and less managers and occupant inthe industry were less required in the industries. Only the mostexperienced and competent in specified field fitted who were majorlythe whites.
