Absenteeism: Absenteeism can be a serious employment problem. It is estimated that absenteeism reduces potential output by more than 10%. Two economists launched a research project to learn more about the problem. They randomly selected 100 organizations to participate in a 1-year study. For each organization, they recorded the average number of days absent per employee and several variables thought to affect absenteeism. Analyses and slope provided below. Use these analyses and the slope coefficient for U/M Rel to describe how the relationship between the union and the management affects absenteeism. Use these analyses and the slope coefficient for Av Shift to describe how organizations who offer shift work compare to those that do not.
