Use the following listed chest deceleration measurements (in g, where g is the force of gravity) from samples of small, midsize, and large cars. Use a 0.05 significance level to test the claim that the different size categories have the same median chest deceleration in the standard crash test. Do the data suggest that larger cars are safer? Use the Kruskal-Wallis test in R. Please state the hypothesis, present a screenshot of the R output of your test, and give your conclusion in the context of the problem.
