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 california public university system is that 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 is the correct hypotheses to test in an attempt to support the claim of this researcher? let {\mu_1 represent the average time it takes females to complete a baccalaureate degree in the california public university system, and let {\mu_2 represent the average time it takes males to complete a baccalaureate degree in the california public university system.

choose one answer.

a. h_0: \mu_1-\mu_2=0 \\ h_a: \mu_1-\mu_2> 0
b. h_0: \mu_1-\mu_2=0 \\ h_a: \mu_1-\mu_2< 0
c. h_0: \mu_1-\mu_2=0 \\ h_a: \mu_1-\mu_2 \neq 0
d. h_0: \mu_1-\mu_2> 0 \\ h_a: \mu_1-\mu_2 \neq 0
e. none of the above
