Question

30. Listed below are head injury data from crash test dummies. These measurements are in hic, which denotes a standard head injury criterion. The TI-84 Plus display presents the results of a one-way ANOVA to determine whether different car categories have the same mean.

Head Injury in a Car Crash (hic)
Small Cars	290	406	371	544	374	501	376	499	479	475
Medium Cars	245	502	474	505	393	264	368	510	296	349
Large Cars	342	216	335	698	216	169	608	432	510	332

(a) Is the design balanced? Why or why not?

(b) ConstructanANOVAtable.

(c) Can you conclude that the different car categories have the same mean? Use the 0.05 level of significance. (you do not need to show all the steps of the hypothesis test, but explain your decision.)
