Answer:
The width of the classes for a frequency distribution or histogram is the closest to 25 .
Step-by-step explanation:
This is the complete question:
The following data represent the recent sales price (in $1,000s) of 24 homes in a Midwestern city.
187 125 165 170 230 139 195 229
239 135 188 210 228 172 127 139
122 181 196 237 115 199 170 239

Suppose the data on house prices will be grouped into five classes. The width of the classes for a frequency distribution or histogram is the closest to ?
Solution:
The formula to find the width of the class is:
Width of class = (maximum value − minimum value) / (number of classes)
maximum value from the given data is: 239
minimum value from the given data is: 115
So width of the classes for a frequency distribution or histogram is calculated as:
Width = (239 − 115) / 5
= 124 /5
= 24.8
This can be rounded up to 25
So Width = 25
