Quizplus · Accepted Answer

To find the relative frequency of salespeople who earn $1,600 or more, we need to add the frequencies of the last two classes in the distribution (1600-1999 and 2000-2399) and then divide by the total number of salespeople in the distribution.

Frequency of salespeople earning $1,600 or more = 24 + 12 = 36
Total number of salespeople = 117

Relative frequency = (36/117) x 100% ≈ 30.8%

Therefore, the best choice is D, which represents the relative frequency of salespeople who earn $1,600 or more as 30.8%.
