Out of 250 randomly selected "Greek" students, 200 voted in the last election. Out of 500 randomly selected "Not Greek" students, 140 randomly selected "Not Greek" students voted in the last election. How would we write the alternative hypothesis? Group of answer choicesA. Ha: pA - pB = 0
B. Ha: pA - pB > 0
C. Ha: pA - pB < 0
