Engineering Stats: What is the correct analysis to test this hypothesis?
I have to do 2-3 tests on this data using: RCBD, ANOVA, hypoth test(t-test,z-test), chi-squared,Taguchi, or regression analysis. How do i test this hypothesis. H0: Pay for engineers are the same across graduating school?
I don\'t need to have the problem solved I need to know the best methods to test the H0.

H0: Pay for engineers are the same across different location
Ha: Atleast two are different
(two sided chi square test)
Two-way Contingency Table
?2 = 0.367, df = 9, ?2/df = 0.04 , P(?2 > 0.367) = 1.0000
As p value is very high, accept null hypothesis.
Conclusion: Pay for engineers are the same across different location
