In a market test of a new chocolate raspberry coffee a poll

In a market test of a new chocolate raspberry coffee, a poll of 400 people (sample 1) from Dobbs Ferry showed 250 preferred the new coffee. In Irvington, 170 (sample 2) out of 350 people preferred the new coffee. To test the hypothesis that a higher proportion of people in Dobbs Ferry prefer the new coffee, what is the alternate hypothesis?
H1: 1 < 2
H1: 1 > 2
H1: 1 = 2
H1: 1 2

Solution

H1: 1 > 2 is alternative hypothesis because it has strict inequality sign.
