Quizplus · Accepted Answer

To find the relative frequency of those salespersons that earn $1,600 or more, we need to add up the frequencies of the given classes that earn $1,600 or more and divide it by the total frequency.

The classes that earn $1,600 or more are:
$1,600 - $1,999: frequency = 32
$2,000 - $2,399: frequency = 27
$2,400 or more: frequency = 13

Total frequency = 112

Relative frequency = (32+27+13)/112 = 0.308 or 30.8%

Therefore, the best choice is D.
