Chapter 13, Problem 26RE
Blood alcohol content (BAC) is measured in grams of alcohol per deciliter of blood. For instance, a BAC reading of 0.08% (a level that is considered legally intoxicated in most states) means that one deciliter of the person’s blood contains 0.08 gram of alcohol. A toxicologist recorded the times elapsed, in hours, until the blood alcohol levels of eight adults who had consumed various amounts of alcohol were less than 0.005%. The results are given in the table.
a. Find the regression equation and linear
b. Use the equation to predict the time it would take for a person with a BAC of 0.06% to reach a BAC level of less than 0.005. Round to the nearest tenth.
