Question 5: (2 Points Each = 10 Points): Identify the type of bias in each of thes scenarios: A. Differential Loss to Follow-Up B. Interviewer Bias C. Non-Differential Misclassification D. Differential Misclassification E. Selection Bias F. Recall Bias 1. There are multiple researchers questioning study participants about their food intake histories during interviews throughout a 10-year cohort study. They do not use standardized questionnaires, and questions are left to the discretion of the interviewers. 2. Researchers recruit "volunteers" to participate in a study about whether they may have been exposed to a hazardous chemical at their workplace, and the researchers then seek "volunteer" controls from another workplace without chemicals. 3. In a study of adolescents (teenagers) who developed leukemia, mothers whose teens developed leukemia as well as a matched control group of mothers whose teens did not develop leukemia were asked about their alcohol consumption and use of pain medications during pregnancy. 4. Study participants in a long-term cohort study no longer participate in the data collection process because they have moved, and the researchers do not have their new addresses in the study database. This happened more often in the exposed group compared to the unexposed group. 5. Researchers decide to form a case-control study for hypertension (high blood pressure) based solely on whether they had a one-time high blood pressure reading in their doctor's office. No attempts were made to find out whether patients were already taking medications or doing other personal interventions such as lowering fat or salt in the diet. This has resulted in a set of imbalanced cases and controls for the study for their hypertension status
