Objective II
To find out the causes of global
warming in Erhoike community
warming in Erhoike community
Step 1: Formulate Hypothesis
Ho:
There are no causes of global warming in Erhoike community
There are no causes of global warming in Erhoike community
Step II: Choose Alpha (α) and Degree of Freedom (df)
Let
α =0.05
α =0.05
Df =(C-1)(R-1)
= (2-1)(3-1)
=1×2=2
Therefore, α=0.05, at 2df=5.991

Step VI: Apply Decision Rule
Since x2 calculated 20.4 is
greater than table value of x2 0.05=5.991, the researcher therefore
rejected the null hypothesis and concluded that there are causes of global
warming in Erhoike community.
