Driver error can be listed as the cause of approximately 54% of all fatal auto accidents, according to the American Automobile Association. Thirty randomly selected fatal accidents are examined, and it is determined that 14 were caused by driver error. Using α = 0.05, is the AAA proportion accurate?

We know that most auto accidents are due to driver error. If we move to self-driving (autonomous) vehicles we can expect far fewer accidents and injuries. As autonomous cars become the norm and individual driver error becomes less of an issue, will auto liability insurance still be needed? How will it change? Please explain.   How is insurance underwriting likely to change with the move to autonomous vehicles? How will telematics make a difference? Please explain.

A random sample of 48 traditional, mixed-use, pedestrian-friendly neighborhoods and 54 postwar, auto-oriented neighborhoods, all with comparable household income levels, revealed the following. The traditional neighborhoods averaged 14.6 daily vehicle miles traveled (VMT) per adult household member, with a standard deviation (uncorrected for bias) of 6.2 VMT. The auto-oriented neighborhoods averaged 18.9 VMT per adult household member and an (uncorrected) standard deviation of 7.3 VMT. Using the five-step hypothesis testing process, test the hypothesis of New Urbanists, that traditional neighborhoods...
