Question

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 4.5
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
Construct a grouped frequency distribution table for this data, using class intervals of size 0.5 starting from the interval 2 - 2.5.

Answer 1

Answer:

a grouped frequency distribution table

Step-by-step explanation:

a grouped frequency distribution table is as below :

Class Frequency Greater Than  Less than

2-2.5 2                           40                      2

2.5-3 6                         38              8

3-3.5 14                            32             22

3.5-4 11                          18              33

4-4.5 4                      7                      37

4.5-5 3                      3                      40
