Step-by-step explanation:
29, 32, 48 , 50 , x, x + 2,72,78 , 84 ,
95
are given observations.
number of observations (n) = 10 [ even ]
median = average ( n/2 , n/2 +1 )th terms
= Ave( 5th & 6th ) terms
= (x + x + 2 )/2 =
= ( 2x + 2)/2
= x + 1 ----(1)
median = 63 ( given ) --(2)
from (1) & ( 2), we get
x + 1 = 63
x= 62
I hope this helps you.
