A job candidate at a large job fair can be classified as unacceptable, provisional, or acceptable. Based on past experience, a high-quality candidate is expected to get 80 percent acceptable ratings, 15 percent provisional ratings, and 5 percent unacceptable ratings. A high-quality candidate was evaluated by 100 companies and received 60 acceptable, 25 provisional, and 15 unacceptable ratings. A chi-square goodness-of-fit-test was conducted to investigate whether the evaluation of the candidate is consistent with past experience. What is the value of the chi- square test statistic and number of degrees of freedom for the test? (15–5)² (25-15)? (60-80)? X = with 2df 15 80 B (15–5)ª (25–15) (60-80)? x? = with 3df 15 80 (15–5)² (25–15)? (60–80)? X = with 99df 15 80 D x² (5–15)? (15–25)? (80-60)? 15 with 2df 25 60 (5–15)?
