A company manufactures car batteries of a particular type. The lives (in years) of 40 such batteries were recorded as follows: Construct a grouped frequency distribution table for this data
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)
2-2.5 2 2.5-3 6 3-3.5 14 3.5-4 11 4-4.5 4 4.5-5 3 Total 40
