Data for head injury measurements (in HIC, which is a standard head injury criterion) from samples of small, midsize, and large cars involved in the standard crash test were used to produce the accompanying ANOVA table. Using a 0.05significance level, test the claim that the different size categories have the same mean head injury measurement. Does the size of a car appear to affect head injuries?
