The refationship between the body mass index (mass) and the thickness of skin folds around the triceps (triceps) in mm is studied among women of Pima Indian heritage by using a least squares regression. Since the lowest body mass index on record is 18.2 we decide to subtract this value from body mass index value. A linear model is generated: Triceps = 13.3247+0.7943 mass. What is the interpretation of 0.7943 in this new model? a. On average, a woman with a bmi of 18.2 has a skin fold of 0.7943mm at the tricep. b. As the thickness of the tricep skin fold of a Pima Indian woman increases by 1cm, the body mass index increases by 1 . c. As the body mass index increases by 1, the thickness of the tricep skin fold of a Pima Indian woman decreases by 0.7943mm. d. As the thickness of the tricep skin fold of a Pima Indian woman decreases by 1cm, the body mass index increases by 1. e. As the body mass index decreases by 1, the thickness of the tricep skin fold of a Pima Indian woman increases by 0.7943mm
