If the range of a distribution were 89 and the data were reported as whole numbers, what would the width of the class interval be if one chose to group the distribution into approximately 14 class intervals

Answer: The width of the class interval would be 6.

Step-by-step explanation:

Formula to find the class width :

[tex]\text{Class width }=\dfrac{\text{Range} }{\text{Number of classes}}[/tex]

Given : The range of a distribution were 89 .i.e. Range = 89

The approximate number of class intervals = 14

Then, the width of the class interval would be

 [tex]\dfrac{89}{14}=6.35714285714\approx6[/tex]

[Round to the nearest integer.]

Hence, the width of the class interval would be 6.
