1600,...1290.... 1,090
760.... 1400.... 2,100
880.... 1390.... 1,830
1,950.. 1850.... 1,250
1,220... 950.... 1,920
------------------
Ho: The means are the same
Ha: At least one of the means is not the same as the others
---------------
I ran an ANOVA Test against the three sets of data and got the
following results:
test statistic: F = 0.9367
p-value: 0.4188
-----
Conclusion: since the p-value is less than 5%, reject Ho.
Not all the means are equal
