Answer 2

15

Explanation:

Let the added number be x

Data set is

9,12,17,15,13

After adding x data set will be,

x,9,12,17,15,13

Number of digits=6

6 is an even number

Arrange the following number in ascendig order

9,12,13,x,15,17

Hence, the median will be=[(n/2)+(n/2

+1)]÷2

Hence, the median will be=[(6/2) th term+(n/2

+1) th term]÷2

Hence, the median will be= (3 th term +4 th term)÷2

=

`(13+x)/(2)`=14

13+x=14×2

13+x=28

x=28-13

x=15

Hence, the added number is 15.
