Application Blood alcohol concentration (BAC) is a measure of the amount of alcohol in a person’s bloodstream.
27
Application Blood alcohol concentration (BAC) is a measure of the amount of alcohol in a person’s bloodstream. A BAC of 0.04% means that a person has 4 parts alcohol per 10,000 parts blood in the body All 50 states have now set .08% blood alcohol concentration(BAC) as the legal limit for driving under the influence (DUI) or driving while impaired (DWI). For commercial drivers, a BAC of .04% can result in a DUI or DWI conviction nationwide.
29
Application Relative risk is defined as the likelihood of one event occurring divided by the likelihood of a second event occurring If an individual with a BAC of 0.02% is 1.4 times as likely to have a car accident as an individual that has not been drinking, the relative risk of an accident with a BAC of 0.02% is 1.4

Application
31
Research indicates that the relative risk of a person having an accident with a BAC of 0.02% is Find the constant.
32
Using this value of k, what is the relative risk if the concentration is 0.17%?
34
If the law asserts that anyone with a relative risk of 5 or more should not have driving privileges, at what concentration of alcohol in the bloodstream should a driver be arrested and charged with DUI?
