Q3 Table below presents a case control study with cases of liver cancer matched on age, gender, and history of smoking. Table 1 Dose level of solvent A Liver cancer No liver cancer Total (cases) (controls) Low 181 1323 1504 _ 222 1098 1320 403 2421 2824 a) Calculate and interpret the appropriate measure of association (2 points). b) Suppose that 10% of cases were misclassied as exposed to the low level and 15% of controls were misclassied to the low level of solvent A. What type of information bias is this called (2 points) and what is the impact of this type of bias on the measure of association (3 points)? c) What broad category of bias does misclassication fall under (1 point)
