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; H_A: p?₁ ≠ p?₂ 

B. H₀: p?₁ = p?₂ = 0.50; H_A: p?₁ ≠ p?₂ ≠ 0.50 

C. H₀: π₁ = π₂ = 0.50; H_A: π₁ ≠ π₂ ≠ 0.50 

D. H₀: π₁ = π₂; H_A: π₁ ≠ π₂
