Economists at USF are researching the problem of absenteeism at U.S. firms. A random sample of 100 U.S. organizations was selected to participate in a 1-year study. As part of the study, the economists had collected data on the following two variables for each company: shiftwork available (Yes or No), and union-management relationship (Good or Poor). As part of their analyses, the economists wanted to determine whether or not a company makes shiftwork available depends on the relationship between union and management. The collected data are shown below:

Relation

In order to determine whether the shiftwork responses depend on the relationship responses, a two-way chi-square analysis should be conducted. When calculating the test statistic, what values for the expected counts should be used in the calculation?
◦ E₁₁ = 36, E₁₂ = 33, E₂₁ = 64, E₂₂ = 67
◦ E₁₁ = 11.88, E₁₂ = 21.12, E₂₁ = 24.12, E₂₂ = 42.88
◦ E₁₁ = 0.065, E₁₂ = 0.036, E₂₁ = 0.032, E₂₂ = 0.018
◦ E₁₁ = 11, E₁₂ = 22, E₂₁ = 25, E₂₂ = 42
