Questiоns 3-6. In а cаse-cоntrоl study, reseаrchers are looking to investigate the relationship between previous occupational exposure to trichloroethane (found in paint removers and industrial solvents) and Parkinson’s disease. They randomly sample 75 individuals with Parkinson’s disease through a support group and 150 individuals from the community. To determine exposure they ask participants recently diagnosed with Parkinson’s disease a series of standardized questionnaires via telephone regarding their occupations and potential exposures in the workplace to trichloroethane 20 years before. Pretend you are reviewing a grant written to fund the study above. If, in the approach section of the grant it comes to light that that the cases came from a Parkinson's support group in New York, but the controls came from a community sample in California, what would you say?
