Following their traffic study, the state lowered the speed limit on the U.S. state highway route through the small town from 45 mph to 35 mph. A follow-up study was done to determine whether or not reducing the speed limit reduced the number of accidents. Both studies were conducted for the same amount of time. Create a Pareto diagram. Interpret results. Carelessness/Inattention Visibility Obscured Excessive Speed Driving under the Influence High traffic volume 4 22 8 12 2 3.
