What is the lower class limit for the first class?

Answer 1

Answer:

the answer of this question is 40

Answer 2

Answer:

Here according to the question we get that the lowest frequency is of 40 while the class gap is zero since the value of the classes are single.

As, the value of the classes are single then there will be no gap in the classes thus the lowest class or here the fish length corresponding to the lowest frequency will give us the lowest class limit which in this case is 20.
