Researchers at a large nutrition and weight management company are trying to build a model to predict a person's body fat percentage from an array of variables such as body weight,height,and body measurements around the neck,chest,abdomen,hips,biceps,etc.A variable selection method is used to build a simple model.SPSS output for the final model is given below. A graph of the residuals versus the predicted values is given below. What assumption do we check with this graph?
A)The Normality of the error terms
B)The independence of the residuals
C)The constant variance assumption of the predicted values
D)None of the above
