with mean m expressed as a proportion of the sample
standard deviation
NOTE It is used to set the confidence limits of the

NAPOMENA Student raspodjela se koristi da se postave
granice pouzdanosti srednje vrijednosti populacije,
posebno u slučajevima gdje je srednja vrijednost
procijenjena iz malih uzoraka. Vrijednost t se dobiva iz
