The standard deviation of scores for the tenthlevel is 215 and is denoted as option A.
This is defined as the measure of the amount of variation or dispersion of a set of values.
We were told that score of 3,540 points is 2 standard deviations above the mean score of 3,110 therefore,
3,110 + 2 s= 3,540
2 s = 3,540 - 3,110
2s = 430
s = 430/2
s = 215
