A survey of high school students was done to examine whether students had ever driven a car after consuming a substantial amount of alcohol (1=yes, 0=no). Data was collected on their sex (male/female), race (White/non-White), and grade level (9,10,11,12).

Question

A survey of high school students was done to examine whether students had ever driven a car after consuming a substantial amount of alcohol (1=yes, 0=no). Data was collected on their sex (male/female), race (White/non-White), and grade level (9,10,11,12). Researchers realized that the impact of race on consuming alcohol before driving might vary by grade level and decided to fit the following model.

Variable	Coding = 1 if
Intercept
Sex ()	Female
Race ()	Black
Grade level (	9^th grade 10^th grade 11^th grade [Reference = 12^th grade]

Attached is the logistic model

1. Compute the OR of drinking before driving for students who self-reported as Black versus non-Black in the 9^th grade, adjusting for gender.

2. Compute the OR of drinking before driving for students who self-reported as Black versus non-Black in the 12^th grade, adjusting for gender.

3. Compute the OR of drinking before driving for someone in the 9^th grade versus 12^th grade for a student who self-reported as Black, adjusting for gender.
