In addition to the traditional bachelor of engineering (BE) degree, many universities worldwide offer a bachelor of technology (BTech) degree for students who wish to work as an engineering technician. There is a perception that BTech students are not as “academically strong” as BE students. This issue was addressed in the International Journal of Continuing Engineering Education and Lifelong Learning (Vol. 13, 2003). The researchers compared BE and BTech students at an Australian university on a variety of academic-related outcomes. The following table gives the percentages of BE and BTech students who withdrew from two traditionally rigorous courses, engineering mathematics and engineering graphics/CAD.

a. Is there sufficient evidence of a difference between the percentage of BE students and percentage of BTech students who withdraw from engineering mathematics? Test using α = .05.
b. Is there sufficient evidence of a difference between the percentage of BE students and percentage of BTech students who withdraw from engineering graphics/ CAD? Test using α = .05.
