Question

use the given minimum and maximum data entries, and the number of classes, to find the class width, the lower class limits, and the upper class limits. minimum = 9, maximum = 73, 6 classes
the class width is

Explanation:

Step1: Calculate class - width formula

The formula for class width $w$ is $w=\frac{\text{maximum}-\text{minimum}}{\text{number of classes}}$, rounded up to the next whole number.
Here, $\text{minimum}=9$, $\text{maximum}=73$, and $\text{number of classes}=6$. So, $w = \frac{73 - 9}{6}=\frac{64}{6}\approx10.67$.

Step2: Round up class - width

Since the class width must be a whole number, we round up $10.67$ to $11$.

Answer:

$11$
