<PRE><B>Question 1091409</B>
A trainee risk manager for an investment bank has been told that the level of risk is directly related to the industry type (manufacturing, retail, financial). For the data presented in table below, test if level of risk is associated with industrial class. Use 5% level of significance.
----
Ho: row and column factors are independent
Ha: row and column factors are dependent
Industrial class 
Level of risk	Manufacturing	Retail	Financial
Low	              81	  38	   16
Moderate	      46	  42	   33
high	              22	  26	   29
------
I ran the Chi^2 Test on my TI-84 to get
Chi^2 = 28.88
and p = 8.28x10^-6
-----
Conclusion:: Since p is less than 0.05, reject Ho
Conclusion:: The row and column factors are dependent
