<PRE><B>Question 304846</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 these three
vehicles?

Crash Damage ($)
Goliath			 Varmint 			Weasel
1,600			 1,290				 1,090
   760 			 1,400				 2,100
   880			 1,390				 1,830
1,950			 1,850				 1,250
1,220			   950 				 1,920
--------------------------------------------------------------
Ho: the means are all equal
Ha: at least one of the means is different
----
I ran an ANOVA test on the data to get the following:
---
test statistic: F = 0.9367
p-value: 0.4188
---
Since the p-value is greater than 5%, fail to reject Ho.
----
The test results support saying the results of the crash
tests are the same for the three vehicle types.
