When one is constructing a table representing the frequency distribution of weights (lb) of discarded textile items from Data Set 23 in Appendix B, the first two classes of a frequency distribution are 0.00-0.99 and 1.00-1.99. What is the class width?

To find: The class width for the frequency distribution.
Answer to Problem 1CQQ
The class width for each class is 1.00.
Explanation of Solution
Given info:
The data shows the frequency distribution for the weights (lb) of discarded textile items. Also, first two class intervals are 0.00-0.99 and 1.00-1.99.
Calculation:
Class width:
The class width is distance between the two successive lower limits of the class intervals.
The formula for class width is,
Substitute 1.00 for “Second lower class limit” and 0.00 for “First lower class limit”
Thus, the class width for each class is 1.00
