Appendix V

Objective IV

To
find out possible measures to reduce the health implication of pesticides on
man and environment

Step I: Formulate Hypothesis

Ho: There
are no possible measures to reduce the health implication of pesticides in
Obiaruku

Ha: There
are possible measures to reduce the health implication of pesticides in
Obiaruku

Step II: Choose Alpha (a) and Degree of Freedom (DF).

DF =
(R – 1) (C – 1)

= (3 – 1) (2 – 1)

Df = 2 x 1 = 2

Where
R = row, C = column

α =
0.05 at 2df = 5.991

Step III: State Test Statistics

Computed x2 table IV

O	E	O – E
170	151.7	18.30	334.89	2.21
150	151.7	-1.70	2.89	0.02
135	151.7	-16.70	278.89	1.84
30	48.3	-18.30	334.89	6.93
50	48.3	1.70	2.89	0.06
65	48.3	16.70	278.89	5.77
Total				X2 = 24.65

Step VI: Apply Decision Rule

Since
x2 calculated 24.65 is greater than the table value of x2
0.05 = 5.991 at 2df the researcher therefore rejected the null hypothesis and
concluded that there are possible measures to reduce the health implication of
pesticides on man and his environment.
