The values that exist two standard deviations above and below the mean are 681 and 265.
<h3>How to determine the values?</h3>
The given parameters exist:
Mean = 473
Standard deviation =104
The values above and below the mean exist calculated utilizing:

In this case n = 2.
So, we have, 
The value above is:
x = 473 + 2
104 = 681
The value below is:
x = 473 - 2
104 = 265
Therefore, the values that exist two standard deviations above and below the mean are 681 and 265.
