The following equation is the result of performing a multiple regression analysis:
Job performance = 10 + (5 = job knowledge) + (0.7 = conscientiousness), where job knowledge is measured on a scale of 0-5 and conscientiousness is measured on a scale of 0 to 100. Which of the following conclusions is correct?
A) Conscientiousness is less important than job knowledge.
B) If a person scored 5 on job knowledge and 100 on conscientiousness he or she would have the maximum predictive score possible.
C) Neither job knowledge nor conscientiousness predicts performance.
D) If a person scored 0 on both job knowledge and conscientiousness, his or her predictive score is 0.
