Suppose a team of researchers studied the association between a low-fiber diet and the 5-year risk of colorectal cancer among residents of Hillsborough County aged 50 and older using a prospective cohort study. The researchers sampled 2.5% of all Hillsborough County residents with a low-fiber diet and 3% of all Hillsborough County residents without a low-fiber diet. When it comes to colorectal cancer status, the researchers sampled 2% of all Hillsborough County residents with colorectal cancer and 4% of all Hillsborough County residents without colorectal cancer.   Based on the information presented above, will there be selection bias in the estimate of the effect of low-fiber diet on colorectal cancer (yes/no)?
