The parametric case involving the means of paired samples is a case of dependent samples, where the difference between the pairs is analyzed. Therefore, the null hypothesis is that the mean difference is equal to zero (H0:μD = 0), and the alternative hypothesis is that the mean difference is not equal to zero (H1:μD ≠ 0). The other options represent different situations, such as independent samples (A and D) or proportions (C), and do not apply to the paired samples scenario.
