One of the many concerns of college students today is the time required for them to graduate with a baccalaureate degree (BA or BS). Current estimates in the public university system are that it takes an average of slightly over 5 years for a student to complete a baccalaureate degree. One researcher suggests that males take a significantly longer average time than females to complete a baccalaureate degree.

What are the correct hypotheses to test in an attempt to support the claim of this researcher? Let11represent the average time it takes females to complete a baccalaureate degree in the public university system, and let22represent the average time it takes males to complete a baccalaureate degree in the public university system.
