When cigarettes are burned, one
by-product in the smoke is carbon
monoxide. Data is collected to determin
e whether the carbon monoxide emission can be
predicted by the nicotine level of the cigarette.
It is determined that the relationship is
approximately linear when we predict carbon monoxide,
C
, from the nicotine level,
N
.
Both variables are measured in milligrams. The formula for the model is
