Objective II
To
examine the consequences of pesticides on farm products and the environment
examine the consequences of pesticides on farm products and the environment
Step I: Formulate Hypothesis
Ho:
Pesticides do not have any consequences of farm products and the environment.
Pesticides do not have any consequences of farm products and the environment.
Ha:
Pesticides have any consequences of farm products and the environment.
Pesticides have any consequences of farm products and the environment.
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 III: State Test Statistics
Where RT = Row total
CT = Column total
GT = Grant total

Step VI: Apply Decision Rule
Since
x2 calculated 22.94 is greater than the table value of x2
0.05 = 5.991 at 2df the researcher therefore rejected the null hypothesis and
concluded that pesticide have consequences on farm product and the environment
in Obiaruku community.
