Question

the median of data: 56,58,63, x - 5,x+1, 75, 81, 85 is 67, then find the value of x and also find its mean. ​

Answer 1

Answer:

Median =12[n2th term+(n2+1)th term]  (when n is even)

Here,

n=8 which is even

Therefore,

Median =12[4th term+5th term]

67=12(x−5+x+1)

67=2x−42

2x−4=67(2)

2x=134+4

2x=138

x=1382

x=69
