Employers want to know which days of the week employees are
absent in a five-day work week. Most employers would like to
believe that employees are absent equally during the week. Suppose
a random sample of 70 managers were asked on which day of the week
they had the highest number of employee absences. The results were
distributed as in Table. For the population of employees, do the
days for the highest number of absences occur with equal
frequencies during a five-day work week? Test at a 0.05%
significance level.
Day | Observed Frequency |
---|---|
Monday | 16 |
Tuesday | 13 |
Wednesday | 13 |
Thursday | 17 |
Friday | 11 |
