Question:
a. Find the predicted value and residual for an athlete who has BP = 85, BP60 = 10, and LP200 = 20.
b. Find the prediction equation for athletes who have LP200 = 20, and explain how to interpret the slope for BP_60.
c. R2 = 0.656 for the multiple regression model is not much larger than r2 = 0.643 for the bivariate model with LP200 as the only explanatory variable. What does this suggest?
