In the United States, it is illegal to drive with a blood alcohol concentration of 0.08 or higher. (A blood alcohol concentration of 0.08 indicates 0.08% alcohol in the blood.) The scatter plot shows the relationship between the number of one-ounce beers consumed per hour by a 200-pound person and that person's corresponding blood alcohol concentration. Also shown is a line that passes through or near the data points. Blood Alcohol Concentration Based y on a Body Weight of 200 Pounds 0.14 0.12 0.10 (7, 0.121) 0.08 0.06 0.04 (3, 0.053) 0.02 2 3 4 5 7 Number of Beers per Hour Source: National Highway Traffic Safety Administration a.
