Question: Suppose you sample from two large populations and find sample proportions of p? 1 = 120/300 and p? 2 = 125/500. Suppose you are going
Suppose you sample from two large populations and find sample proportions of p?1 = 120/300 and p?2 = 125/500. Suppose you are going to complete a test of significance using these proportions to see whether there is strong evidence that the population proportions differ. Which of the these are the appropriate hypotheses for this test?
A. H0: p?1 = p?2; HA: p?1 ≠ p?2
B. H0: p?1 = p?2 = 0.50; HA: p?1 ≠ p?2 ≠ 0.50
C. H0: π1 = π2 = 0.50; HA: π1 ≠ π2 ≠ 0.50
D. H0: π1 = π2; HA: π1 ≠ π2
