12. Researchers at VCU studied fatal auto accidents between cars in which one has an air bag and the other does not. They found that in 73% of all such fatal crashes the driver of the air bag vehicle was responsible for the accident. Suppose that you obtain police records of fatal auto accidents. A random sample of 41 such accidents showed that 33 were the fault of the driver of the air bag vehicle. Does this indicate that the population proportion of such accidents in which the driver of the air bag vehicle was at fault is higher than 73%? Use a 5% level of significance.
