Question

In a bumper test, three types of autos were deliberately crashed into a barrier at 5 mph, and the resulting damage (in dollars) was estimated. Five test vehicles of each type were crashed, with the results shown below. Research question: Are the mean crash damages the same for these three vehicles?

Crash Damage ($)
Goliath	Varmint	Weasel
1,660	1,270	1,040
790	1,490	2,110
880	1,380	1,800
1,980	1,810	1,280
1,210	990	1,920
