Ho= Diabetes(D) and Obesity(O) are not associated

Ha= Diabetes(D) and Obesity(O) are associated

• If p<0.05, D and O are associated, and they are correlated

• If p>0.05, D and O are associated, and they are correlated

• If p<0.05, D and O are associated, and they maybe correlated

• If p<0.05, D and O are not associated, but they are correlated
