Document Summary

Question: a survey about participation in greek life is administered to college students in ga. H0: emory = uga vs. ha: emory uga. H0: pemory puga vs. ha: pemory = puga. H0: pemory = puga vs. ha: pemory puga. Already know the sample, don"t need to make hypothesis on it. Is the major associated with a double major? ons. Question: if there was no association between major type and whether or not a student double majored (i. e. h0 true), how many double majors would you expect to see in the humanities. If there is no difference among divisions, then it should be that the same as a random group from the proportion of the total. Expect the same proportion of the sample as seen in the greater population. If there"s no association, we know how to fill in a table based on proportion. All you"d have to do is make a comparison.
