You can put this solution on YOUR website! A math test was given a sample of the scores yielded the following results

If you are assigned this problem you probably have formulas to
find the mean, variance and std.
You should do the arithmetic at least once.
A good calculator would do it in a few seconds:
mean = 46.875
variance = 1066.52
std = sqrt(variance) = 32.658
