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 1 represent the average time it takes females to complete a baccalaureate degree in the California public university system, and let 2 represent the average time it takes males to complete a baccalaureate degree in the California public university system

Solution

Difference = mu (1) - mu (2) Estimate for difference: -0.270000 95% CI for difference: (-0.755150, 0.215150) T-Test of difference = 0 (vs not =): T-Value = -1.13 P-Value = 0.266 DF = 36
