Males and females were tested about what they would do if they received a $100 bill by mail, addressed to their neighbor, but wrongly delivered to them. Would they return it to their neighbor? Of the 81 males sampled, 63 returned the envelope to their neighbor and of the 142 females sampled, 129 returned the envelope. Does the data indicate that the proportions that returned the envelope are higher for females compared to males at a 5% level of significance?
