nitial BAC was zero. The number (between 1 and 9) of 12 ounce beers to be drunk was assigned to each of the subjects by drawing tickets from a bowl. Thirty minutes after consuming their final beer, students ad their BAC measured by a police officer of the OSU police department. The officer also administered road sobriety test before and after the alcohol consumption. This involved performing four simple asks, graded on a scale of 1 to 10 (ten being a perfect rating), demonstrating coordination: balancing on one foot, touching the tip of one's nose with a forefinger, placing one's head back with one's eyes closed, nd walking heel to toe. The police officer was not aware of how much alcohol each subject had consumed. A simple linear regression was conducted to predict BAC and the regression equation and ther- quared are shown in the graph below. Use the results to answer the following questions. BAC vs Number of Beers 0.2 0.18 y = 0.018x- 0.0127 R2 = 0.7998 0.16 0.14 0.12 0.1 0.08 0.06 0.04 0.02 10 BAC
