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
