Given,
The number of total students and faculty is 213.
From the table,
The number of students opposed to the change is, n(student oppose) = 44.
The number of faculty members opposed to the change is, n(faculty oppose) = 20.
The number of faculty members favor to the change is, n(faculty favour) = 11.
