Consider the regression equation from the previous question, that estimated the relationship between blood alcohol content (y) and number of beers consumed (x). Recall that A guy named Dudley has this regression equation written on a scrap of paper in his pocket. Dudley goes out drinking and has 4 beers. He calculates that he is under the legal limit (0.08) so he decides to drive to another bar. Unfortunately Dudley gets pulled over and confidently submits to a road-side blood alcohol test. He scores a blood alcohol of 0.085 and gets himself arrested.
Based on your knowledge of statistics and regression analysis, how would you explain what happened?
a.The regression equation was not correctly estimated.
b.Dudley incorrectly calculated his blood alcohol level.
c.The testing device malfunctioned.
d.Even though the predicted blood alcohol level of 0.0593 was below the legal limit, his residual of 0.0257 pushed it above.
