17) The following table is obtained from a random sample of 30 absences:

Day                        Mon   Tue   Wed   Thur   Fri
Number Absent     5        5        2         8     10

You wish to test the claim that the absences occur on the five days with equal frequency. What is the value of the X² test statistic? The observed frequencies and the column for the expected frequencies are shown below:

A) X2 = 3.8     B) X2 = 6.333     C) X2 = 9.5     D) X2 = 4.75

B) X2 = 6.333
