The manager of High Point Sofa and Chair, a large furniture manufacturer located in North Carolina, is studying the job performance
ratings of a sample of 15 electrical repairmen employed by the company. An aptitude test is required by the human resources
department to become an electrical repairman. The manager was able to get the score for each repairman in the sample. In addition,
he determined which of the repairmen were union members (code = 1) and which were not (code = 0). The sample information is
reported below.
