Chapter 13, Problem 61CP

a.

To determine

Calculate the predicted value of the maximum number of pounds that an athlete can bench press and the corresponding residual, if they have $\text{maxBP}=85$, $\text{BP60}=10$ and $\text{LP200}=20$.

b.

To determine

Calculate the prediction equation for an athlete with $\text{LP200}=20$.

Interpret the corresponding slope of BP60.

c.

To determine

Explain the implication of the value $R^2=0.656$ for the multiple regression, in comparison to the value $r^2=0.643$ for the simple regression.
