<PRE><B>Question 263874</B>
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 the three vehicles?

760 1,400 2,100
880 1,390 1,830
1,950 1,850 1,250
1,220 950 1,920
--------------
Ho: u1=u2=u3
Ha: At least one of the means is different
---------------
I ran an ANOVA program on my TI calculator to get:
ts: F = 0.93665..
p-value: 0.4188
df=2
------------------
Conclusion:
Since the p-value is 41%, fail to reject Ho
Statistically, the means are the same for the three cars.
