9.2 A reduction in force.
A human resources manager wants to assess the impact of a planned reduction in force (RIF) on employees over the age of 40. (Various laws state that discrimination against this group is illegal.) The company has 850 employees over 40 and 675 who are 40 years of age or less. The current plan for the RIF will terminate 120 employees: 90 who are over 40, and 30 who are 40 or less. Display these data in a two-way table. (Be careful. Remember that each employee should be counted in exactly one cell.)
