Lucky Administers an Integrity Test at Garden Haven, a Supplier

Lucky administers an integrity test at Garden Haven, a supplier of lawn and garden supplies, in order to screen out potential thieves or dishonest workers. Howard, another Garden Haven employee, frantically finds Lucky and tells him the test is no good because several applicants just told him they faked their answers. What should Lucky do?

A) nothing because faking is common and does not influence the correlation between scores and performance
B) do away with unreliable integrity tests and ascertain the qualities of applicants from face-to-face interviews
C) stop using the integrity test and switch to the more reliable and less invasive polygraph test instead
D) hire a group of proctors who are trained to catch cheaters to oversee test administration
E) invalidate all of the tests taken during the testing period referred to by Howard
