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: Organize the Data
We first need to list the battery lives provided:
- 2.6, 3.0, 3.7, 3.2, 2.2, 4.1, 3.5, 4.5, 3.5, 2.3, 3.2, 3.4, 3.8, 3.2, 4.6, 3.7, 2.5, 4.4, 3.4, 3.3, 2.9, 3.0, 4.3, 2.8, 3.5, 3.2, 3.9, 3.2, 3.2, 3.1, 3.7, 3.4, 4.6, 3.8, 3.2, 2.6, 3.5, 4.2, 2.9, 3.6

### Step 2: Determine Class Intervals
We will create class intervals of size 0.5 starting from 2 to 2.5. The intervals will be:
