A company published the results of a study that found that arrogant workers are more likely to have poor performance ratings. Suppose that 15% of all full-time workers exhibit arrogant behaviors on the job and that 13% of all full-time workers will receive a poor performance rating. Also, assume that 10% of all full-time workers exhibit arrogant behaviors and receive a poor performance rating. Let A be the event that a full-time worker exhibits arrogant behavior on the job. Let B be the event that a full-time worker will receive a poor performance rating. Are events A and B independent? Why? Are the events A and B independent? Explain. A. No, because if workers exhibit arrogant behaviors, they are more likely to receive a poor performance rating. B. No, because if workers exhibit arrogant behaviors, they will receive a poor performance rating. C. Yes, because if workers exhibit arrogant behaviors, they are more likely to receive a poor performance rating. D. Yes, because if workers exhibit arrogant behaviors, they are neither more nor less likely to receive a poor performance rating.
