Objective IV
To
find out possible measures to reduce the health implication of pesticides on
man and environment
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
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
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)
(R – 1) (C – 1)
= (3 – 1) (2 – 1)
Df = 2 x 1 = 2
Where
R = row, C = column
R = row, C = column
α =
0.05 at 2df = 5.991
0.05 at 2df = 5.991

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.
