A scientist was interested in studying if students beliefs about illegal drug use change as they go through college. The scienti
st randomly selected 104 students and asked them before they entered college if they thought that illegal drug use was wrong or o.k. Four years later, the same 104 students were asked if thought that illegal drug use was wrong or o.k. The scientist decided to perform McNemar's test. The data is below. What is the proportion of students that thought that is was wrong after college?
