The author randomly selected cars in those states and the results are given in the accompanying table. Use a 0.01 significance level to test the claim of independence between the state and whether a car has front and rear license plates. Does it appear that the license plate laws are followed at the same rates in the three states? Click here for the information of license plates and each state.
