Question

the median of the following observation arranged in ascending order is 22 find x 8,11,13,15,x+1,x+3,30,35,40,43

Answer 1

Answer:

total no of observation. 10

n=even

median= n/2 + n+1/2 th observation

= 10/2 + 10+1/2

5th + 6th observation/2

x+1+x+3/2

2x+4/2

but median is 22

2x+4/2 is 22

2x+4 is 44

2x is 44-4

2x is 40

x is 40/2= 20
