A bridge on a small, rural road is designed to hold 10 cars whenit is full and its maximum continuous weight that the bridge isdesigned to hold is 39,000 pounds. Assume that the average Americancar weighs 3750 pounds and that American cars' weights have astandard deviation of 200 pounds. If the bridge is fully loadedwith 10 cars, what is the probability that it will be overloaded?Hint: Think about what the bridge designer thought the averageweight of car that the bridge would hold would be and remember todraw a picture of the distribution to determine how you aretreating the probability!
Do you think that the bridge in the previous question is safe touse? Why or why not?
