A regression between foot length (Y variables in cm) and height (X variables in inches) for 33 students resulted in the following regression equation:

$y=10.9+0.23x$

One student in the sample was 73 inches wall with a foot length of 29cm.

a) The predicted foor length for this student is __cm

b) Residual for this student's __cm

The regression equation is :

$\hat{Y}=10.9+0.23X$

Where Y = foot length

X = Height

a) For $x=73,Y=29$

For $x=73,\hat{Y}=10.9+0.23(73)=27.69$

b) Residual $=Y-\hat{Y}=29-27.69=1.31$

$\hat{Y}=10.9+0.23X$

Where Y = foot length

X = Height

a) For $x=73,Y=29$

For $x=73,\hat{Y}=10.9+0.23(73)=27.69$

b) Residual $=Y-\hat{Y}=29-27.69=1.31$
