Employers particularly 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.
That is, the average number of times an employee is absent
is the same on Monday, Tuesday,
Wednesday, Thursday or Friday. Suppose a sample of 20
absent days was taken and the days
absent
were distributed as follows:
Number of Absences
Monday
5
Tuesday
4
Wednesday
3
Thursday
Friday
2
6
At a = 0.05, perform a chi-square goodness of fit test to determine if the distribution is uniform for all
days of the work week.
