Question

Use the minimum and maximum data entries and the number of classes to find the class width, the lower class limits, and the upper class limits. min = 14, max = 121, 8 classes

Answer 1

The class width is
`C_w \approx 13`

Explanation:

From the question we are told that

The upper class limits is
`max = 121`

The lower class limits is
`min = 14`

The number of classes is
`n = 8 \ classes`

The class width is mathematically represented as

`C_w = (max - min)/(n )`

substituting values

`C_w = (121 - 14)/(8 )`

`C_w = 13.38`

`C_w \approx 13`

Since
