A company manufactures car batteries of a particular type. The lives (in years) of 40 such batteries were recorded as follows: 2.6 3.0 3.7 3.2 2.2 4.1 3.5 4.53.5 2.3 3.2 3.4 3.8 3.2 4.6 3.72.5 4.4 3.4 3.3 2.9 3.0 4.3 2.83.5 3.2 3.9 3.2 3.2 3.1 3.7 3.44.6 3.8 3.2 2.6 3.5 4.2 2.9 3.6 Construct a grouped frequency distribution table for this data, using class intervals of size 0.5 starting from the interval 2 - 2.5.

Explanation

To construct a grouped frequency distribution table for the given data of battery lives, we will follow these steps:

### Step 1: Identify Class Intervals
We are given that the class intervals should start from 2 to 2.5 and have a size of 0.5. The class intervals will be:
1. 2.0 - 2.5
2. 2.5 - 3.0
3. 3.0 - 3.5
4. 3.5 - 4.0
