Question

the following observation has been arranged in ascending order. if the median of data is 63find the value of x :-

29 ,32,48 ,50 ,x ,x+2 ,72 ,78 ,84 ,95

Answer 1

X=62

total terms=10

Therefore, median= mean of (10/2)th and (10/2 +1)th term

= mean of 5th and 6th term

=(X+X+2)/2

Therefore,

63=(X+X+2)/2

63=2(X+1)/2

63=X+1

X=62
