Both the t-test and the z-test allow for calculation of a p-value, which can be used to determine the statistical significance of the results. Option A is false because the t-distribution depends on the sample size and assumes normality, while the z-distribution is based on the population standard deviation and assumes normality. Option B is false because both tests assume normality and the z-test also assumes that the population standard deviation is known.
