Answer 1

Step-by-step explanation:

Since the frequency distribution is not continuous, so firstly we shall make it continuous.

Here, , then , which lies in interval 144.5 – 153.5.

Median class = 144.5 – 153.5

So, and

Now, Median =

=

=

= 144.5 + 2.25

= 146.75

Hence median length of the leaves is 146.75 mm.
