Since we have a six-day workweek, we would expect each day to have an equal amount of absenteeism if absenteeism is distributed evenly. Thus, the expected frequency would be the total absenteeism divided by the number of days in the week: (237/6) ≈ 39.5. Since we need whole numbers, we would round down to 39 for each day. Therefore, the expected frequency is 10 (since 39 × 6 = 234, which is closest to the actual number of absences, 237).
