To find the expected frequency, we first find the total number of absences in the sample: 
2 + 2 + 2 + 1 + 1 + 1 = 9 
Then we divide by the number of days in the week (6) to get the expected frequency: 
9 ÷ 6 = 1.5 
We round up to the nearest whole number to get an expected frequency of 2 absences per day. 
Therefore, the best choice is B because it matches the expected frequency we calculated.
