You can put this solution on YOUR website! Starting with the data values 80 and 100, add three data values to the sample so that the mean is 94, the median is 94, and the mode is 94.
------
If the mode is 94 there must be two 94's in the set
Let the 5th data element be "x".
----
Solve for x so the mean is 94:
[80 + 94+94 + 100 + x}/5 = 94
386 + x = 470
x = 84
---
The set is {80,84,94,94,100}
