Please Assist with part c!

A highway safety institution conducts experiments in which cars are crashed into a ed ba er at 40 mph n he institute's 40 mph offset test 40% of the total width of each vehicle strikes a barrier on the driver's side. The bar ers deformable face is made of aluminum honeycomb, which makes the forces in the test similar to those involved in a frontal offset crash between two vehicles of the same weight, each going just less than 40 mph. You are in the market to buy a family car and you want to know if the mean head injury resulting from this offset crash is the same for large family cars, passenger vans, and midsize utility vehicles (SUVs). The data in the accompanying table were collected from the institute's study. Complete parts (a) through (d) below EEB Click the icon to view the data table Head Injuries C. Ho: ars -Hyans-suvs and H1: at least one mean is different (b) Normal probability plots indicate that the sample data come from normal populations.

No, because the populations are not normally distributed. C. No, because the largest sample standard deviation is more than twice the smallest sample standard deviation. OD.

Explanation / Answer

applyng one way ANOVA on above data:
