A large stock-brokerage firm wants to determine how successful its new account executives have been at recruiting clients. After completing their training, new account execs spend several weeks calling prospective clients, trying to get the prospects to open accounts with the firm. The following data give the numbers of new accounts opened in their first 2 weeks by 10 randomly chosen female account execs and by 8 randomly chosen male account execs. At a = 0.05, does it appear that the women are more effective at generating new accounts than the men are?
