Question

If the median of the data : 15, 17, x - 1, x + 5, 31, 36 is 22, then find Mean​

Answer 1

Step-by-step explanation:

Median =

15,17,x-1, x+5,31,36

Median which is middle value Is (x-1+ x+5)=22

Find X=

x-1 +x+5

2x +4 =22

2x = 22-4

x=18/2

x=9

Now mean =

15 + 17 +8 ( I.e x-1) + 14 (i.e x+5) + 31 +36

= 121

Average is Sum of all values/Total no of values

so

121/6

=20.17
