Answer :
The 3rd class limit is (8-9.9).
The class interval for the given data, with the 3rd class limit as (8-9.9), is 1.9.
The class interval for the given data can be determined by finding the difference between the upper limit and the lower limit of the class. In this case, the 3rd class limit is (8-9.9).
To find the class interval, we subtract the lower limit (8) from the upper limit (9.9):
9.9 - 8 = 1.9
Therefore, the class interval is 1.9.
To summarize:
Answer: 1.9
To find the class interval, we subtract the lower limit (8) from the upper limit (9.9), resulting in a difference of 1.9. Thus, the class interval is 1.9.
Conclusion: The class interval for the given data, with the 3rd class limit as (8-9.9), is 1.9.
