In this solution demonstrated below “Quantitative Methods” for statistical analysis has been used proficiently by our expert.


A case-control study was conducted to investigate the hypothesis that adult alcohol consumption is associated with the risk of liver cancer.  For the study, 6000 patients under 55 years of age with incident liver cancer, diagnosed between 2007 and 2010, were identified from the Detroit SEER registry records.  A random sample of 1,200 individuals with a similar age, sex, and race distribution as the cases was also identified.  All of the study participants were interviewed to assess average adult alcohol consumption and other lifestyle factors, including smoking and exercise.  Average adult consumption was determined as drinking at least 12 ounces of alcohol per day.  The data are as follows.

Average alcohol consumption per day Liver Cancer Cases Controls Total
≥ 12 ounces 410 450 860
< 12 ounces 190 750 940
Total 600 1,200 1,800
