Question
Males and females were asked what they would do if they received a $100 bill in the mail that was addressed to their neighbor, but had been incorrectly delivered to them. Of the 70 males sampled, 55 said yes they would return it to their neighbor. Of the 130 females sampled, 120 said yes. The overall question is: Is this sufficient evidence to say that the two true proportions are different? Choose the best null and alternative hypothesis for this test. O Null: (p1 - p2) = 0 vs Alternative (p1 - p2) > O. O Null: (p1 - p2) = 0 vs Alternative (p1 - p2) not = 0. O Null: (mean 1 - mean 2) = 0 vs Alternative (mean 1 - mean 2) not = 0. %D %3D O Null: (p1 - p2) = 0 vs Alternative (p1 - p2) < 0. %3D
