Answer 2

Answer: The third quartile of the distribution is 23.

Explanation:

First we write the data in ascending order:

4,5,8,10, 11,11, 13,15,16, 18, 18, 18, 21, 23, 24, 24, 25, 27, 31, 32

Since there are 20 terms:

First half is for First Quartile :

4,5,8,10, 11,11, 13,15,16, 18

Second half is for third Quartile:

18, 18, 21, 23, 24, 24, 25, 27, 31, 32.

So, Value of third quartile would be

`Q_3=(5^(th)+6^(th))/(2)\\\\Q_3=\dfarc{24+24}{2}\\\\Q_3=(48)/(2)\\\\Q_3=24`

Hence, the third quartile of the distribution is 23.
