Quizplus · Accepted Answer

To calculate the pooled proportion, we need to combine the number of employees and the number of absences from both plants. 
Total number of employees = 800 + 1200 = 2000 
Total number of absences = 120 + 144 = 264

Pooled proportion = Total number of absences / Total number of employees 
Pooled proportion = 264/2000 = 0.132

Therefore, the best choice is C) 132.
