Reference no: EM131888895

In a study that looked as the effect on car crash severity, researchers found the average mean speed in fatal accidents was 42 miles per hour with a standard deviation of 15 miles per hour. Legislators are debating lowering the 70 mile per hour speed on highways based on the argument that the higher speed will result in more fatalities. What percentage of fatal accidents occur based on the researchers data at a speed of 70 or more miles per hour?
