Question 711486
What is the missing data if the mean is 60, the mode 52 and the range 28 in the following data set ---,52,---,---,72,78. 
=======
If the range is 28 the minimum element must be 78-28 = 50
----
If the mode is 52, one of the missing elements must be 52
---
Let the other missing element be "x".
===
Using mean = 60 solve:
(50 + x + 52 + 52 + 72 + 78)/6 = 60
------
(x + 304) = 360
---
x = 56
