Noble is frustrated with the many migrant workers he hires from a specific country who work for only a short time and then quit or are terminated for performance or disciplinary reasons. He wants to screen out any future applicants from that country to reduce costs and improve the chances of effective hiring choices. Which of the following is true?

• Noble's opinion is sufficient to allow not hiring applicants from a specific country.
• If Noble's opinion is substantiated with data, then he can choose not to hire applicants from a specific country.
• Noble can use specific hiring criteria to limit the chances of hiring employees with the same issues he has been experiencing, but he must apply the criteria to all applicants.
• Noble cannot use prejudice in his hiring decisions; he must take equal consideration for all applicants regardless of their tendency to quit early or cause discipline problems.
