Answer 1

Answer:

i think it's 0.2

but i'm not sure about it sryyy

Answer 2

The class size of each interval is 0.2

Given:

The frequency table is

5 - 5.2 5.2 -5.4 5.4 - 5.6 5.6 - 5.8 5.8 - 60

34           4             4             4            6        

To find:

Class size of the grouped frequency table

Solution:

Formula used:

Class size = Upper limit - Lower limit

     

Using the above formula,

The class size of each class interval can be calculated as follows

For class interval, 5 - 5.2

Class size = 5.2 - 5 = 0.2

For class interval, 52 - 5.4

Class size = 5.4 - 5.2 = 0.2

For class interval, 5.4 - 5.6

Class size = 5.6 - 5.4 = 0.2

For class interval, 5.6 - 58

Class size = 5.8 - 5.6 = 0.2

For class interval, 5.8 - 6.0

Class size = 6.0 - 5.8 = 0.2

Here the class interval for each class interval is the same

Therefore,

The class size of each interval is 0.2
