Alona [7]

Answer:

Option C is correct.

Step-by-step explanation:

We have been given total 8 data

Data is : 12,15,18,20,23,23,28

Here, n=7

Median is \frac{n+1}{2}=\frac{7+1}{2}=4th term

Median is 20.

When one data is added n=8

The median of  even number of data is  

median=\frac{\frac{n}{2}\text{th and}\frac{n}{2}+1\text{th}}{2}

Median is \frac{8}{2}\text{th and}\frac{8}{2}+1th

Median is 4\text{th and}5th

4th terms is 20

5th terms is 23

Since, median should not be change hence,

Median will be 20.

Therefore, option C is correct.
