The safety of cars is determined from a variety of tests. It is suggested that larger cars are safer because they have lower chest deceleration measurements. But are those visual differences significant? Smaller measurements correspond to less trauma to the crash test dummies. Therefore, are larger cars safer in the sense that they have lower chest deceleration measurements? Also, are there significant differences with type of car, foreign or domestic? Use a 0.05 significance level to test whether the size of the car (small, medium, large) and type of car (foreign, domestic) are related to lower chest deceleration measurements. The probability under the null hypothesis is?
