How does drinking beer affect the level of alcohol in our blood? The legal limit for driving in all states is $0.08\%$. In a study, adult volunteers drank different numbers of cans of beer. Thirty minutes later, a police officer measured their blood alcohol levels.

Given that the legal limit for driving in all states is $0.08\%$

In the provided question, the legal limit for driving in all states is stated. In a study, adult participants drank varying amounts of beer cans, and their blood alcohol levels were measured thirty minutes later by a police officer. The amount of alcohol consumed is the explanatory variable, while the blood alcohol level is the response variable. Because the values of the following variables used in the experiment are not provided, we only see both variables.

So, because the values aren't stated, we can't tell much about how consuming beer impacts the amount of alcohol in our blood, but we do know that alcohol increases the amount of alcohol in our body, though we can't say whether it rises or decreases after thirty minutes.
