The accompanying table lists the number of complaints received about each of a sample of 10 reservation agents during the 6 months before naps were encouraged and during the 6 months after the policy change.

b. What assumptions must hold to ensure the validity of the test?

c. What variables, not controlled in the study, could lead to an invalid conclusion?
