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 "165 up to 190." -that is,{x;165 ≤ x < 190}.The frequency of this class is _____.
A) 6/24 
B) 7/24 
C) 6 
D) 7

Quizplus · Accepted Answer

To find the frequency of the class {x;165 ≤ x < 190}, we need to count how many observations in the data set fall within this range. Since there are 24 homes total, and this class includes all values greater than or equal to 165 but less than 190, we need to count how many values in the data set are at least 165 but less than 190. Looking at the data set, we can see that exactly 7 values fall within this range: 170, 173, 175, 180, 185, 187, and 188. Therefore, the frequency of the class is 7, or D.
