Use the following data set : 7 , 17, 30, 18, 24, 16, 3, 18,7...

Step 1: Given information
Given data set:
7 , 17, 30, 18, 24, 16, 3, 18,7
Step 2: Answer is given by,
Arrange the data in ascending order, we have
3, 7, 7, 16, 17, 18, 18, 24, 30
We know that,
${\displaystyle Midrange=\frac{Maximumvalue+Minimumvalue}{2}}$
${\displaystyle Midrange=\frac{30+3}{2}}$
${\displaystyle Midrange=\frac{33}{2}}$
${\displaystyle Midrange=16.5}$ Therefore,
Option (b) is correct.
Answer ${\displaystyle =\text{16.5}}$
