Answer 1

exclusive form, the lower and upper limits are known as true lower limit and true upper limit of the class interval.

● In inclusive form, class limits are obtained by subtracting 0.5 from lower limitand adding 0.5 to the upper limit.

Thus, class limits of 10 - 20 class interval in the inclusive form are 9.5 - 20.5.
