After settling a lawsuit, the XYZ Corporation decided to investigate whether there might be significant differences in benefits allotted among groups of their employees. Their staff conducted a simple random sample process and found the following data regarding the use of personal leave (i.e., vacation, sick or unpaid) for the years 2010 – 2014.
Low Medium High
(50 hours/yr or less) (51-200 hours/yr) (More than 200 hours/yr)
Men 20,150 19,875 1,225
Women 2,590 3,875 3,150
Please conduct a statistical test to determine whether men are different than women regarding the extent of their use of personal leave at XYZ Corporation in recent years. Identify the hypotheses you are using; the rejection criterion employed; and explain your answer.
