Ho: Row and Column factors are independent
Ha: Row and Column factors are not independent
I ran a Chi-Sq Test of the 3 by 4 set of data and got the following:
---
Chi-Sq = 54.1768
p-value = 0.000000000048325
===================================================
Since the p-value is less than 1%, reject Ho
Conclusion: The test results do not support Ho.
===================================================
