The following regression equation was obtained from this study: Y—hat=—0.0127+0.0180X. The legal limit to drive is a blood alcohol content (BAC) of less than .08. If a student consumed 5 beers the model predicts that his BAC should be approximately equal to: /‘\ .09 above the legal limit C .0027 below the legal limit C .0027 above the legal limit C .0733 above the legal limit ATTACHMENT PREVIEW Download attachment Screen Shot 2019-12-11 at 9.26.07 AM.png Question 49 2 pts The relationship between the number of beers consumed (X) and blood alcohol content (Y) was studied in male college students by using least squares regression. The following regression equation was obtained from this study: Y—hat=—0.0127+0.0180X. The legal limit to drive is a blood alcohol content (BAG) of less than .08. After consuming 5 beers, one student had a BAC of.09. What is the residual for this student?
