Explanation:
Given
The histogram
Required
The class width
The question is poorly formatted, as the histogram cannot be read. So, I will answer your question with the attached histogram
The class width is:
[tex]Width = Upper - Lower\ Limits[/tex]
Using the first class, as reference:
[tex]Lower\ Limits = 1[/tex]
[tex]Upper\ Limits = 4[/tex]
So, the class width is:
[tex]Width = 4 -1[/tex]
[tex]Width = 3[/tex]
