Quizplus · Accepted Answer

To find the relative frequency of workers who took 10 or fewer sick days, we need to add up the frequency of workers who took 10 or fewer sick days and divide it by the total number of workers. 
Frequency of workers who took 10 or fewer sick days = 75 + 60 + 40 + 10 = 185 
Total number of workers = 200 
Relative frequency of workers who took 10 or fewer sick days = 185/200 = 0.925. Therefore, the answer is B.
