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 = 94, 7 classes the class width is (type a whole number.)

Explanation:

Step1: Calculate class width formula

Class width = $\frac{\text{Maximum}-\text{Minimum}}{\text{Number of classes}}$, rounded up to the next whole number.

Step2: Substitute values

Here, maximum = 94, minimum = 9, and number of classes = 7. So, $\frac{94 - 9}{7}=\frac{85}{7}\approx12.14$. Rounding up, the class width is 13.

Answer:

13
