Explanation / Answer

Number of employees that were absent on at least 11 days = 13+8+3

= 24

Percentage of employees that were absent on less than 16 days = (47+17+13) x 100 / (47+17+13+8+3)

= 77x100/88

= 87.50%

Relative frequency of 16-20 class interval = 8/88

= 0.09

Midpoint of class interval with smallest frquency = (21+25)/2

= 23

Mean absent days = (3x47 + 8x17 + 13x13 + 18x8 + 23x3)/88

= 7.49 days
