Final answer:
A low risk driver is not characterized by reactions such as standing up from a seated position or a car accelerating. These options do not represent typical low risk driving behaviors, which are more focused on safety practices. To validate the AAA statistic, a hypothesis test can be conducted with the provided accident data.
Step-by-step explanation:
A low risk driver is characterized by behaviors that promote safety and reduce the likelihood of being involved in an accident. When considering actions that are not typical of a low risk driver, options such as a person standing up from a seated position and a car accelerating while driving do not directly relate to driving reactions. Instead, a low risk driver's reactions would typically include maintaining safe following distances, adhering to speed limits, and being attentive to road conditions and traffic signs.
To address the statistical question, the proportion of fatal auto accidents caused by driver error according to the AAA is 54%. In the given sample of thirty accidents, 14 were caused by driver error. To determine whether the AAA proportion is accurate, a hypothesis test can be conducted. The null hypothesis would state that the proportion is equal to 0.54, while the alternative hypothesis would state that the proportion is different from 0.54. Using a significance level of α = 0.05, a test statistic can be calculated to judge this hypothesis against the sample data.
