In a market test of a new chocolate raspberry coffee, a poll of 400 people from Dobbs Ferry showed 250 preferred the new coffee. In Irvington, 170 out of 350 people preferred the new coffee. To test the hypothesis that there is no difference in preferences between the two villages, what is the null hypothesis? Multiple Choice H0: π1 > π2 H0: π1 ≠ π2 H0: π1 < π2 H0: π1 = π2
