A researcher is investigating the association between smoking habits and the development of respiratory diseases. The researcher collected data on smoking status (non-smoke and smoker) and the occurrence of respiratory diseases (yes or no). 80 smokers developed respiratory disease, 120 smokers did not develop respiratory disease, 40 non-smokers developed respiratory disease, and 160 non-smokers did not develop respiratory disease. Calculate the expected count for smokers who have respiratory disease.
