Answer :
i) It can be observed that the length of leaves is represented in a discontinuous class
interval having a difference of 1 in between them.
Therefore, \(\frac{1}{2} = 0.5\) has to be added to each upper class limit and also have to subtract 0.5 from the class limits so as to make the class intervals continuous.
