1. What do you think is the research objective of the above study? My answer: To conduct a study on the effects of bio-behavioral interventions on the pain level of patients who had an appendectomy.? please let me know if my objective is correct2. What should be the sampling criteria (inclusion and exclusion) for the study? Justify your answer. My answer: The patients should have undergone appendectomy?I didn't put the inclusion and exclusion cause I don't think it's needed. Please advise3. What sampling design/ technique should be utilized in the study? Justify your answer. Should I use Simple Random Sampling or Stratified Random Sampling. Divide the sample into three groups4. Conduct a hypothesis testing if you were comparing deep breathing exercise and progressive muscle relaxation. Show the step-by-step process of hypothesis ? a. Null and alternative hypothesesThis is my answer: We want to test the null hypothesis that there is no significant difference between the use of deep breathing exercise and progressive muscle relaxation in the pain level of patients who had appendectomyBelow are the answers: pls explain further why two tailed test to be use and explain further how to come up with the level of significance which i know is alpha value as 0.05 Also for the test statistic, critical region, computation of test statistical and p value, decision and conclusio
