Parents want to find out which days of the week their children are away in a 5 day school week. Most parents believe that their children are equally away throughout the week. Suppose a random sample of 60 teachers are asked on which day of the week they had the most number of children absences, the results are shown below. For the population of the children, do the days for the most number of absences occur with equal frequencies during a 5 day school week? Test at a 5% significance level.

NO. OF ABSENCES :

Monday: 15

Tuesday: 12

Wednesday: 9
