I conducted a study for a project where 20 students were surveyed asking them if they drink coffee or another caffeineted beverage before schoolwork and if so do they belive it helps their academic performance. 10 students did and 10 students did not. 4 students believed it helped and 6 students did not think it helped. I am to use either a (Test of Association hypothesis test), a (Goodness of Fit hypothesis test), a (Two sample hypothesis test for means) or a (Two sample hypothesis test for proportions). Which test do you think would be most appropriate?
