You can put this solution on YOUR website! There is no one sample, no one sample mean x-bar, and no one sample standard
deviation s. Different people would get different samples from the same
population. They would get different sample means and different sample
standard deviations. So it all depends on the sample. You find the mean,
then find the difference between each one and the mean, square these
differences, add them, divide by one less than the number in the sample
and take the square root. Realize that there are many many possible
samples from a given population, and therefore many many different values
for s.
