Answer:
number of observation 'n' = 8
if the number of observation is even then :
median = 1/2 [value of (n/2)^th term + value of (n+1/2 )^th term]
= 1/2 [value of (8/2)^th term + value of (8+1/2 )^th term]
= 1/2 [value of (8/2)^th term + value of (9/2 )^th term]
= 1/2 [value of 4th term + value of 5th term]
= 1/2 [x +2 + 60]
= 1/2 [x+62]
= 1 * x + 62 / 2
= x + 62 / 2
= x + 31
The value of x = - 31
