The heights (in cm) of 30 students of class IX are given below:

155, 158, 154, 158, 160, 148, 149, 150, 153, 159, 161, 148, 157, 153, 157, 162, 159, 151, 154, 156, 152, 156, 160, 152, 147, 155, 163, 155, 157, 153.

Prepare a frequency distribution table with 160-164 as one of the class intervals.

The heights (in cm) of 30 students of class IX are:

155, 158, 154, 158, 160, 148, 149, 150, 153, 159, 161, 148, 157, 153, 157, 162, 159, 151, 154, 156, 152, 156, 160, 152, 147, 155, 163, 155, 157, 153.

To do:

We have to prepare a frequency distribution table with 160-164 as one of the class intervals.

Solution:

Maximum height $= 163\ cm$

Minimum height $= 147\ cm$

Range $=163 - 147$

$= 16$

The required frequency distribution is:
