Organizations are interested in identifying variables that will predict the performance of job applicants. Two known predictors of job performance are personality (i.e., conscientiousness) and years of formal education. Researchers at the University of Arkansas believe that number of previous jobs held by job applicants may also predict performance. However, in contrast to conscientiousness and years of formal education, the researchers anticipate that number of previous jobs held will have an inverse relationship with job performance. To test their ideas, the researchers asked 125 car salespeople from Fletcher Honda to fill out a questionnaire that measured (a) their level of conscientiousness (CONSC) on a 7 point scale (1 = strongly disagree and 7 = strongly agree) where higher scores reflect being more conscientious, (b) years of formal education (EDUC), (c) and number of previous jobs held (JOBS). To measure job performance, the researchers used company records to record the number of cars that each salesperson sold in the preceding month (SALES). Use the output below to answer the questions that follow.
