Multiple Choice

State the proper forms of hypotheses for two-sample hypothesis tests.
-For a two-sample hypothesis test for differences in population parameters (1) and (2) , which of the following is the correct form of an upper-tailed test?

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
