The Human Resources Director for a large company is studying absenteeism among hourly workers, A sample of 120 day shift employees showed 15 were absent more than 5 days last year. A sample of 80 afternoon workers showed 18 to be absent 5 times or more last year. We want to test a hypothesis at the .01 level of significance. Based on your computations, would we reject or fail to reject the null hypothesis?
