Question 261376
A math test was given a sample of the scores yielded the following results
88, 34, 18, 20, 4, 68, 1, 10, 99, 35, 61, 92, 67, 62,69, 22 
find the range, standard deviation, and variance for the sample scores.

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
