I want to conduct a study to perform an experiment with the less number of test specimens possible using t-student statistics to validate it.

There are ASTM and ACI standards to the tests but they don't consider the case with small sample or a little number of specimens (they said 30 or more).

I hadn't been able to contact or to look into the standard references for more information 'cause all of those websites try to sell information. Where can I investigate more?

i.e. a x (y + z) = a x y + a x z, where a, y and z are vectors? If possible I'd prefer an intuitive argument, such as a geometric representation, but a rigorous proof would also be helpful.
