Final answer:

The most common cause of collisions is driver error, accounting for around 54% of fatal auto accidents. A hypothesis test can be used to analyze the accuracy of this proportion.

Step-by-step explanation:

Of all the possible causes of collisions, by far the most common cause is B. driver error. Statistics from the American Automobile Association suggest that driver error accounts for approximately 54 percent of all fatal auto accidents. When examining a sample of 30 randomly selected fatal accidents with 14 being caused by driver error, we can perform hypothesis testing using α = 0.05 to determine if the AAA proportion is statistically accurate.
