There is a significant interaction between BMI and genotype on cholesterol levels. True False 5 1 point What is the predicted cholesterol level for an individual who has a BMI of 25 and who has the risky genotype? Round to the nearest whole number. Type your answer.. 1 point The main effect for BMI is not significant (beta coefficient = .1239, p-.9191). What does this mean? BMI is not significantly related to cholesterol. BMI is not significantly related to cholesterol in the normal-genotype group. BMI is not significantly related to cholesterol in the risky-genotype group O BMI should be removed from the model since it's not a significant predictor. 7 1 point The intercept of the model is 199 np/mL. What does this represent? The intercept represents the predicted cholesterol for an individual in the risky genotype group. The intercept represents the predicted cholesterol for an individual in the normal genotype group. O The intercept represents the predicted cholesterol for an individual with = BMI of 0. O The intercept represents the predicted cholesterol for an individual with a normal genotype and = BMI of Q. 1 point Alcohol consumption was treated as a categorical predictor and was dummy-coded. Models were adjusted for age. What was the regression model used? O Pancreatic cancer (yeso] = intercept + age + drinks/week Pancreatic cancer (yeso] = intercept + age + quintile of drinking Pancreatic cancer (yeso) = intercept + age + 1-3 drinks per week (yeso) + 4-20 drinks per week (yeso] + >=21 drinks per week (yeso] O Pancreatic cancer (yesoj = intercept + age + 0-
