A dean of college of business in the Midwest claims that he can correctly identify whether a student is finance major or a music industry management major by the way the student dresses. Suppose in actuality that he can correctly identify finance major 84% of the time, while 16% of the time he mistakenly identifies music industry management major as finance major. Presented with one student and asked to identify the major of this student (who is either a finance or music industry management major), the dean considers this to be a hypothesis test with the null hypothesis being that the student is a finance major and the alternative that the student is a music industry management major.

A) Saying that the student is music industry management major when in fact the student is finance major B) Saying that the student is music industry management major when in fact the student is music industry management major C) Saying that the student is finance major when in fact the student is music industry management major D) Saying that the student is finance major when in fact the student is finance major
