A scientist was interested in determining if students eating habits change as they go through college. One hundred randomly selected students were asked before they entered college if they would consider themselves vegetarians, yes or no. Four years later, the same one hundred students were asked if they would consider themselves vegetarians, yes or no. The scientist decided to perform McNemar's test.
The data is below. Are the assumptions met for McNemar's test?
