Answer the following questions:

A large medical center’s oncology program reported an increased number of cases of pancreatic cancer during a certain month. The hospital’s epidemiologist decided to research the problem. Tumor registry records were searched to identify all cases of pancreatic cancer during a five-year period; cancer patients were matched with patients treated for other diseases during the same five-year period. All subjects in the study were questioned about lifestyle factors including alcohol, tea, and coffee consumption. The resulting data are as follows:
                                 Cancer Patients Other Patients
                                    Men Women    Men Women
LIFESTYLE VARIABLE
Alcohol                            185 120          270    260
Tea Drinking                   140 110          230    225
Coffee Drinking             190 140          270    240

Note: Total nuber of male cancer patients = 200.
         Total number of female cancer patients = 150.
         Total number of male patients (other diseases) = 300.
         Total number of female patients (other diseases) = 300.
