Final answer:
To determine whether the AAA's claim that 54% of fatal auto accidents are caused by driver error is accurate, a hypothesis test using the given sample data and an alpha level of 0.05 should be conducted. Without performing this test, no conclusion can be drawn.
Step-by-step explanation:
The question pertains to whether the proportion of fatal auto accidents caused by driver error, as reported by the American Automobile Association (AAA), is accurate. This association claims that driver error causes 54% of all fatal auto accidents. To test the accuracy of this proportion, a study of 30 randomly selected fatal accidents found that 14 were caused by driver error. To determine if this sample data aligns with the AAA's claim, a statistical hypothesis test could be conducted using the given alpha level (a = 0.05). Without performing the actual hypothesis test, it is not possible to conclusively state whether the AAA proportion is accurate - a complete analysis of the data using the appropriate statistical methods is required to make this determination.
