Step-by-step explanation:

Given : 27,5,11,13,10,8,14,18,7

To find : What is the lower quartile.

Solution : We have given 27, 5, 11, 13, 10, 8, 14, 18, 7.

Step 1 : Arrange in order

5, 7,8,10,11, 13, 14,18, 27.

Step 2 : divide in to Quartile

Lower Q1 = 5,7,8

Middle Q2 = 10, 11, 13.

Highest Q3 = 14,18, 27.

Hence Lower Quartile = 7.

Therefore, Lower Quartile = 7.
