Assignment task
Read the situation carefully and answer the questions. Some questions require computations and brief explanations, while others require constructing tables and graphs.

Question 1. What do you think is the research objective of the above study?
Question 2. What should be the sampling criteria (inclusion and exclusion) for the study? Justify your answer
Question 3. What sampling design/ technique should be utilized in the study? Justify your answer.
Question 4. Conduct a hypothesis testing if you were comparing deep breathing exercise and progressive muscle relaxation. Show the step-by-step process of hypothesis testing:
? Null and alternative hypotheses
? Level of significance
? Test-statistic
? Critical region
? Computation of test statistic and p value
? Decision
? Conclusion
Question 5. Conduct a hypothesis testing if you were comparing the three interventions altogether: deep breathing exercise, progressive muscle relaxation, suggestive hypnosis. Show the step-by-step process of hypothesis testing
? Null and alternative hypotheses
? Level of significance
? Test-statistic
? Critical region
? Computation of test statistic and p value
? Decision
? Conclusion
1. Make an ANOVA summary table for comparing the three interventions (deep breathing exercise, progressive muscle relaxation, suggestive hypnosis). Interpret the summary table.
