A number of nonprofit groups employ fireworks sales as the major fundraiser in the days before the 4th of July. Some of the nonprofits are service groups such as the Veterans of Foreign Wars. Others are intended for support of groups like the cheerleaders from the local high school. The questions are whether those two groups attract different numbers of customers, and whether the gender of the customer is a factor. Among 20 men who bought fireworks during a particular 2-hour period, 14 purchased from service organizations, the other 6 purchased from non-service groups. Of the 18 women who purchased in the same period, 8 bought from service organizations, and 10 from non-service groups. Is the gender of the purchaser related to the group from which the purchase is made?
