Suppose a researcher wanted to see whether an association exists between the amount of fish in the diet and the likelihood of cancer. The researcher follows for 10 years a sample of 250 individuals from each amount of fish in diet category (large, moderate, small, and none) and records whether or not the individuals are diagnosed with cancer during the 10 years. The table below gives three "what if" scenarios, A, B, and C, for the conditional proportion of individuals who are diagnosed with cancer from each amount of fish in diet category and the Mean Group Diff statistic.Which "what if" scenario would produce the smallest p-value?A,B or C.Large proportion Moderate proportion Small proportion None proportion Mean Group Diff A 0.077 0.07 0.076 0.113 0.022 B 0.072 0.073 0.075 0.093 0.011 C 0.078 0.084 0.086 0.102 0.012
