Solution

The correct option is C The distribution is skewed right
From the given plot, we observe that,

the distribution is skewed left.

Hence, the option "The distribution is skewed left" is correct.


Median = 22

Hence, the option "Median = 22" is also correct.


The next option is "The distribution is skewed right"

This is false, since the distribution is skewed left.

IQR = Upper quartile - Lower quartile

Upper quartile = 24

Lower quartile = 14

IQR = 24 - 14 = 10

Hence, the option "IQR = 10" is a true statement.
