In the previous examples, we fit two regression models: $$ \widehat{wgt} = -105.011 + 1.018 \cdot hgt $$ and $$ \widehat{SLG} = 0.009 + 1.110 \cdot OBP \,. $$

Which of the following statements is incorrect?

Possible Answers

A person who is 170 cm tall is expected to weigh about 68 kg.
Because the slope coefficient for $OBP$ is larger (1.110) than the slope coefficient for $hgt$ (1.018), we can conclude that the association between $OBP$ and $SLG$ is stronger than the association between height and weight.
None of the above.
