Answer: missing value = 34

Given data:

• 7,12,23,,X, ,41,49

• Median : 28.5

• X=?

→When we divide the data set into three equal parts , as in (7;12) (23,X) and (41;49)

→ We get that the median is (23+x )/2= 28.5

23+x = (28.5*2 )

x = 57 -23

x =34

Check : 34+23 = 57/2 = 28.5

This means that x = 34 is correct.
