Final answer:
The major cause of fatal traffic accidents in Tennessee involves driver error, which is supported by statistical analysis from the American Automobile Association claiming around 54 percent. Changes over time and considerations for traffic signal installations based on accident rates are also relevant to understanding traffic safety.
Step-by-step explanation:
The question pertains to a major cause of fatal traffic accidents in Tennessee. It is a statistical health question that involves understanding and analyzing data related to traffic accidents and driver error as a cause. According to the American Automobile Association, driver error accounts for around 54 percent of all fatal auto accidents. Testing the accuracy of this claim would involve using hypothesis testing procedures at an alpha level of 0.05, based on data from 30 randomly selected fatal accidents where 14 were caused by driver error.
Over time, statistics have shown changes in the causes of accidental deaths, with motor vehicle crashes and drug overdoses varying in prevalence. For instance, in 1999, there were twice as many deaths from motor vehicle crashes as from drug overdoses, but by 2014, the pattern had reversed. Traffic accidents in certain locations have prompted consideration for traffic signal installations, especially when the number of accidents, including those with fatalities, exceed acceptable limits.
Further statistical analysis of traffic-related injuries and deaths, such as the likelihood of teens being killed in motor vehicle injuries on any given day based on census data, contributes to a comprehensive understanding of traffic safety and the impacts of various factors such as driver error, speeding, and cell phone use on road safety.
