The relationship between number of beers consumed (x) and blood alcohol content (y) was studied in 16 male college students by using least square:s regression. The following regression equation was obtained from this study: y-hat=-0.01270+.0180x The above equation implies that:
each beer consumed increases blood alcohol by.0127
on average it takes 1.8 beers to increase blood alcohol content by .01
After consuming 1 beer, blood alcohol equals .0180.
each beer consumed increases blood alcohol by 0.018
\(\hat{y}=-0.0127+0.0180 x\)
Slope \(=0.0180\)
each beer consumed increases blood alcohol by \(0.018\)
