Objective III
To
examine the health implication of pesticides on human
examine the health implication of pesticides on human
Step I: Formulate Hypothesis
Ho: There
is no health implication of pesticides on human
is no health implication of pesticides on human
Ha: There
is health implication of pesticides on human
is health implication of pesticides on human
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 19.79 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 health implication of pesticides on human.
