A newspaper article on drunk driving cited data on traffic deaths in Rhode Island: "Forty-two percent of all fatalities occurred on Friday, Saturday and Sunday, apparently because of increased drinking on the weekends." What percent of the week do Friday, Saturday and Sunday represent? Are you surprised that 42% of fatalities occur on those days? How might data for the number of cars on the road on those days possibly change or reinforce that perception?
