Dear Statalist,

I would like to compare the means of two very small random samples (n1=3,
n2=7). Both samples were drawn from populations of unknown distribution. Is
Stata's ttest appropriate in such a situation, or does it require the
underlying populations to be normally distributed?  If ttest is not
appropriate, can anyone suggest are more appropriate method for testing the
difference of the means?

Thanks for your help.
