Answer

Accurate probabilities in a hypothesis test or confidence interval about undefended samples are obtained if 2 basic assumptions about the underlying data are correct: 1. The measurements of the underlying distribution of the 2 population from which the samples are draw are normally distributed. 2. The variance of the 2 distributions are approximately equal.
