Question

It is commonly thought that SUVs and vans are safer than cars. If an SUV and a car are in a collision, does the SUV sustain less damage and thus need a cheaper repair? We performed 7 sample crashes of SUVs at 10mph into the rear ends of stopped cars. See the table of normal data below.

SUV into car	SUV damage ($)	Car damage ($)
CRV into Civic	1721	1274
Rav4 into corolla	1434	2327
Tucson into Forte	850	3223
Tiguan into Golf	2329	2058
Patriot into Caliber	1415	3095
Escape into Focus	1470	3386
Rogue into Sentra	2884	4560

Would you be able to say that SUVs are safer since they need less repairs?

Should I use:

confidence intervals
z-score
A cause/correlation/regression or Chi-Squared
hypothesis tests
