Question

effect of blood alcohol concentration (bac) on motor vehicle crashes
about how much higher is the risk of a vehicle crash at a bac of 0.10 percent than a bac of 0.00 percent?
about 5 times as likely
about how much higher is the risk of a vehicle crash at a bac of 0.16 percent than a bac of 0.00 percent?
about 5 times as likely
about 10 times as likely
about 15 times as likely
about 25 times as likely

Explanation:

Step1: Analyze the graph

Look at the y - axis (Relative Likelihood of Causing a Crash) for BAC = 0.00 and BAC = 0.16.

Step2: Estimate the values

At BAC = 0.00, the relative likelihood is close to 1. At BAC = 0.16, the relative likelihood is approximately 25.

Answer:

about 25 times as likely
