Given:

A company manufactures car batteries of a particular type. The lives (in years) of 40 such batteries were recorded.

To do:

We have to construct a grouped frequency distribution table for this data, using class intervals of size \( 0.5 \) starting from the interval \( 2-2.5 \).

Solution:

The grouped frequency distribution table for the given data using class intervals of size 0.5 starting from the interval 2 - 2.5 is as follows:

Lives of batteries (in years)

Number of batteries (Frequency)

2-2.52
2.5-36
3-3.514
3.5-411
4-4.54
