$S = 2.23$
Degrees of Freedom = $17$

Variable Coefficient SE(Coeff) t-ratio P-value
Constant -2.273 0.39 -5.83 <0.0001
Height 1.084 0.24 4.52 <0.0001



Which of the following represents the standard error of the residuals?

A

$0.24$

B

$\cfrac { 0.24 }{ \sqrt { 19 } } $

C

$0.39$

D

$\cfrac { 0.39}{ \sqrt { 19 } }$
