A) H0: population parameter (1) - population parameter (2) ≥ 0 vs. H1: population parameter (1) - population parameter (2) < 0 B) H0: population parameter (1) - population parameter (2) > 0 vs. H1: population parameter (1) - population parameter (2) ≤ 0 C) H0: population parameter (1) - population parameter (2) < 0 vs. H1: population parameter (1) - population parameter (2) > 0 D) H0: population parameter (1) - population parameter (2) ≤ 0 vs. H1: population parameter (1) - population parameter (2) > 0

In an upper-tailed test, the null hypothesis (H0) states that the difference is less than or equal to zero, while the alternative hypothesis (H1) states that the difference is greater than zero.
