Objective III
To find out the health implication of
global warming on the people of Erhoike community
global warming on the people of Erhoike community
Step 1: Formulate Hypothesis
Ho:
there are no health implications of
global warming on the people of Erhoike community
there are no health implications of
global warming on the people of Erhoike community
Ha:
there are health implications of global warming on the people of Erhoike
community
there are health implications of global warming on the people of Erhoike
community
Step II: Choose Alpha (α) and
Degree of Freedom (df)
Degree of Freedom (df)
Let α=0.05
Df=
(C-1)(R-1)
(C-1)(R-1)
=(2-1)(3-1)
=1×2=2
Therefore
α=0.05 at 2df=2
α=0.05 at 2df=2

Step VI: Apply
Decision Rule
Decision Rule
Since 
calculated 37.5 is greater than table
value o
f 0.005=5.991, the researcher therefore
rejected the null hypothesis and concluded that there are health implications
of global warming on the people of Erhoike community.
