Case 1: Dr. Gump wants to test a new drug that helps lower LDL cholesterol levels. He wants to use patients from ABC Medical Center. He uses 100 patients and requires all his patients to take the experimental drug. Case 2: Dr. Rogers and his colleagues conduct an efficacy study on Evamsa (a new drug used to treat chronic lower back pain). Dr. Rogers emphasizes how effective this drug will be to his patients receiving the treatment, but fails to inform them about the possible side effects. Case 3: Dr. Smith wants to use an advanced statistical technique to analyze the data arising from his study. He writes extensively about this statistical technique in the Methods section and gives very little information about the study design and on how study participants were assigned to various types of intervention. Instructions: For each case, identify the problem that may make the study less feasible and justify your claim. For each case, describe the steps you would take to correct the problem and improve the quality of each stud
