Question

Abel Alonzo, Director of Human Resources, is exploring employee absenteeism at the Harrison Haulers Plant during the last operating year. A review of all personnel records indicated that absences ranged from zero to 29 days per employee. The following class intervals were proposed for a frequency distribution of absences. Number of Employees Absences (Days) O-under 10 10-under 20 20-under 30 Which of the following might represent a problem with this set of intervals? There are too few intervals Some numbers between 0 and 29 would not fall into any interval. The first and second interval overlaps. There are too many intervals. The second and the third interval overlap.

Explanation / Answer

Soln.

If the frequency is distributed as in the question there will be only one problem arises as There are few intervals.

Since in a company there will be lot of employees hence we cannot just make intervals of three interval because it cannot completely show how the absenteeism of employees are.

If a employee is absent for 0 days or 1 days And other of 9 days cannot be put in one interval, it should be kept like the employee absent for 1 days or for 5 days can be kept in one interval.

The intervals will never overlap as none of the employee can be absent for two no of days.

As according to question is is evident that every employee falls under 0 to 29 no of days of their absenteeism.so none will fall other than 0 to 29 no of days.
