Question

A data set with whole numbers has a low value of 20 and a high value of 96.

Answer 1

Answer and Step-by-step explanation:

The computation of the class width for a frequency is shown below:

Class width is

$= \frac{Range}{Number\ of\ class} \\\\ = \frac{96 - 20}{7}$

= 10.86

= 11

Now the class limits for a frequency table

Particulars      Lower class limit to upper class limit

First class          20 - 30

Second class    31 - 41

Third class        42 - 52

Fourth class      53 - 63

Fifth class         64  74

Six class           75 - 85

Seventh class   86 - 96
