Question

The median of the following
observations arranged
in ascending order is 15. observations are 10,12,14,x-3,
x, ,x+2,25 then find the x​

Answer 1

Step-by-step explanation:

By using median formula of odd number of observations

(n+1)/2th term

we have

15=(7+1)/2 th term

15=8/2th term

15=4 th term ( which is x-3)

15= x-3

15+3=x

18=x

therefore value of x =18

Since median is 15

∴ middle value is 15

⇒ x − 3 = 15

⇒x = 18
