State the null and research hypothesis in notation.
Calculate the obtained value.
Using an alpha level of 0.05, calculate the critical value.
Compare the obtained value to the critical value, and determine your conclusion.
Homework Answers
Answer #1
null hypothesis:Ho:probation officers from different agencies write same numbers of probation violations.
alternate hypothesis: Ha: probation officers from different agencies write different numbers of probation violations.
from above obtained value =11.66
crtiical value =3.55
Decision:as test statitic is in rejection region we reject null hypothesis
Conclusion: we have sufficient evidence to conclude that probation officers from different agencies write different numbers of probation violations.

months there are increasing complaints by the Production Manager
that delivery times by ABC present higher variability in comparison
to the delivery times by XYZ. The Production Manager is worried
that this variability will make it harder to efficiently schedule
the production process.
