Question: The Independence postmaster suspects that working on ziptronic machines is
The Independence postmaster suspects that working on ziptronic machines is the cause of high absenteeism. More than 10 absences from work without business-related reasons is considered excessive absenteeism. A check of employee records shows that 26 of the 44 ziptronic operators had 10 or more absences and 35 of 120 nonziptronic workers had 10 or more absences. Construct a contingency table for the postmaster. Does the table support the postmaster’s suspicion that working on ziptronic machines is related to high absenteeism?
