A city in the Pacific Northwest recorded its highest temperature at 82 degrees Fahrenheit and its lowest temperature at 23 degrees Fahrenheit for a particular year. Use this information to find the class width if you wish to construct a frequency distribution with 10 classes.

A) 6 degrees Fahrenheit
B) 5.9 degrees Fahrenheit
C) 10 degrees Fahrenheit
D) 3.7 degrees Fahrenheit

Answer :

Final answer:

The class width for the frequency distribution with 10 classes is 5.9 degrees Fahrenheit.

Explanation:

To find the class width for a frequency distribution with 10 classes, we need to calculate the range of the data and divide it by the number of classes. The range is the difference between the highest and lowest temperatures, which is 82 - 23 = 59 degrees Fahrenheit. Dividing this range by the number of classes, 59 / 10 = 5.9 degrees Fahrenheit. So, the class width is 5.9 degrees Fahrenheit.
