A blood alcohol concentration of 0.22 corresponds to near certainty, or a 100% pro bability, of a car accident. R 100% 80% 60% 40% 20% R = 6e2.7x 0.05 0.10 0.15 0.20 0.25 Blood Alcohol Concentration Risk of a Car Accident
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
Medical research indicates that the risk of having a car accident increases
exponentially as the concentration of alcohol in the blood increases. The risk is modeled by R = 6e12.77x, where x is the blood alcohol concentration and R, given as a percent, is the risk of having a car accident. What blood alcohol concentration corresponds to a 17% risk of a car accident? How is this shown on the graph of R in the herewith given Figure?
