To find out, we need to first calculate the mean of the set:

Mean = (4+9+5)/3 = 6

Now we can calculate the deviations of each number from the mean:

4 - 6 = -2
9 - 6 = 3
5 - 6 = -1

If we add up these deviations, we get:

-2 + 3 - 1 = 0

So the sum of the deviations from the mean is indeed zero, making the statement true.
