Answer 1

mode is 21.4 and median 21.2+21.4/2
42.6/2 =21.3

Answer 2

The mean of the distribution is 21.1.

Step-by-step explanation:

The relation between mean, mode and median is given by :

$\text{mean}=\dfrac{1}{2}(3\ \text{median}-\text{mode})$

We have,

Median is 21.2

Mode is 21.4

It is required to find the mean of the distribution. Plugging all the values in above formula such that,

$\text{mean}=\dfrac{1}{2}(3\times 21.2-21.4)\\\\\text{mean}=21.1$

So, the mean of the distribution is 21.1.
