Data analysis and interpretation of results
Objective I
To find out if global warming exist in
Erhoike community
Erhoike community
Step 1: Formulate Hypothesis I
Ho:
Global warming does not exist in Erhoike community
Global warming does not exist in Erhoike community
Ha:
Global warming exists in Erhoike community
Global warming exists in Erhoike community
Step II: Choose Alpha (α) and 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 =0.05 at 2 df=5.991
Step V: Apply Decision Rule
Since x2 calculated 18.12 is
greater than table value of x2 0.05=5.991, the researcher therefore
rejected the null hypothesis and concluded that global warming exist in Erhoike
community near Kokori, Ethiope East Local Government Area of Delta State.
