A study was conducted to investigate the relationship between smoking habits and lung disease among two different groups of individuals (Group A and Group B). The dataset, named smoking_data, contains information about the smoking habits (Non-smoker, Light Smoker, Heavy Smoker) and the presence or absence of lung disease (Yes, No). Please determine if there is a significant association between smoking habits and the presence of lung disease in each group. Provide the necessary SAS code to conduct appropriate test and interpret the results. Additionally, discuss any assumptions made for the test in this context.
