Linear Regression Part C:

Based on the previous research question, researchers would now like to evaluate race as an effect modifier in the relationship between BMI and cholesterol.

Race is a categorical variable, where 0=Non-Hispanic Whites, and 1=Non-Hispanic Blacks

The results of a multivariable linear regression including the interaction term are shown below.

Parameter	Beta	95% CI	P-value
BMI	1.27	1.05, 1.46	0.006
Race	-27.4	-25.2, -29.8	0.002
BMI*Race	0.75	0.60-0.90	0.035
Intercept	205.5	189.6-225.5	0.002

Total cholesterol = 205.5 + 1.27 * BMI -27.4 * Race + 0.75 * BMI * Race

Write out the simplified regression equation for each race.
