Question

if the median of the obseravation x,x+3,x+5,x+7,x+10 is 9 find x ​

Answer 1

✔✔✅Answer ✅✔✔

mean = sum of all observations/total no. of observations

here, mean= x+x+3+x+5+x+7+x+10/5

9 = 5x+25/5

5x+25 = 45

5x = 20

x = 4

so we have data as follows:

4, 7, 9, 11, 14

now using this data find the median
