Question

The following data represent the recent sales price (in $1,000s)of 24 homes in a midwestern city.  Suppose the data are grouped into five classes,and one of them will be "115 up to 140." -that is,{x;115 ≤ x < 140}.The relative frequency of this class is ______.
A) 6/24 
B) 7/24 
C) 6 
D) 7

Quizplus · Accepted Answer

Since we have 5 classes, the total relative frequency should equal to 1. To find the relative frequency of the class "{x;115 ≤ x < 140}", we need to divide the frequency of this class by the total frequency. From the histogram provided, we can see that there are 7 homes within this class. Therefore, the frequency of this class is 7. The total frequency is 24. Thus, the relative frequency of this class is 7/24. So, the answer is B.
