Suppоse а reseаrcher studied the аssоciatiоn between radiation exposure and prostate cancer among Floridian males aged 70+ using a retrospective cohort study. Suppose the researcher sampled 1.4% of Floridan males aged 70+ exposed to radiation and 3.6% of Floridian males aged 70+ not exposed to radiation. When it comes to prostate cancer, the researcher sampled 2% of Floridian males aged 70+ with prostate cancer, and 1% of Floridian males aged 70+ without prostate cancer. Based on the information presented above, will there be selection bias in the estimate of the association between radiation exposure and prostate cancer (yes/no)?
