Comment (by vbraun):
Welch t-test is appropriate, but I don't think this is right:
{{{
err = math.sqrt(s1**2 * (n1-1) / n1 + s2**2 * (n2-1) / n2)
}}}
The t-value should asymptotically be proportional to sqrt(n), so that more
samples = more certain that the observed difference is actual effect (if
sample means and stddevs remain unchanged).
