Question

(6) Sum observations are arranged in the ascending order
as 15, 17. X-1. x + 5, 31, 36. If the median of the
observations is 22, then x = ...​

Answer 1

Answer:

20

Step-by-step explanation:

x-1+X+5/2=22

x-1+X+5=22*2

x-1+X+5=44

2x+4=44

2x=44-4

2x=40

X=40/2

x=20

Answer 2

Answer:

me = n+1/2

me= 6+1/2

= 3.5

median = 3rd +0.5(4th-3rd)

22 = x-1 +0.5(x+5 -(x-1) )

22= x-1 +0.5 ( x+5 - x+1)

22 = x-1 +0.5(6)

22 = x-1 + 3

22-3 = x-1

19 = x-1

19 + 1 = x

x = 20
