The HR department of ABC Manufacturing Industry studied the Job Performance and Job satisfaction
of 120 employees.
The information such as gender and job status were collected.
Given below are the hypotheses of the study
No: There is no significant difference among the level of job satisfaction of the employees when they
are grouped according to educational attainment and length of service.
Na: There is a significant difference among the level of job satisfaction of the employees when they
are grouped according to educational attainment and length of service
α= 0.5, n= 120
Test Statistic = Analysis of Variance (Anova)
Decision rule: Reject the null hypothesis if F computed is greater than F-critical or if the p-value is
less than 0.05. Otherwise, fail to reject the null hypothesis.

Decision: The result in length of service the F value (3.070) is greater than the S squares (2.008) and
the p value (0.31) is less than 0.05, the null hypothesis was rejected. The result in Educational
Attainment the F value (.278) is less than the S squares (.556), and the p value (.300) is greater than
0.05, the null hypothesis was not rejected.
Conclusion: Therefore, there is a significant difference among the level of job satisfaction of the
employees when they are grouped according to length of service, and there is no significant
difference among the level of job satisfaction of the employees when they are grouped according to
educational attainment
No: There is no significant difference among the level of job performance of the employees when they
are grouped according to educational attainment and length of service.
Na: There is a significant difference among the level of job performance of the employees when they
are grouped according to educational attainment and length of service.

Decision: Since the result in length of service, the F value (4.040) is greater than the S squares
(3.344) and p value (0.009) is less than 0.05, the null hypothesis was rejected. The result in
educational attainment, the F value (4.520) is greater than S squares (2.535) and the p value (0.013)
is less than 0.05, the null hypothesis was rejected.
Conclusion: Since the result of length of service and educational attainment reject the null hypothesis,
there is a significant difference among the level of job performance of the employees when they are
grouped according to educational attainment and length of service.
