A clinical trial is run to evaluate the efficacy of a new medication to relieve pain

A clinical trial is run to evaluate the efficacy of a new medication to relieve pain in patients undergoing total knee replacement surgery. In the trial, patients are randomly assigned to receive either the new medication or the standard medication. After receiving the assigned medication, patients are asked to report their pain on a scale of 0-100 with higher scores indicative of more pain. Data on the primary outcome are shown below..9px;=”” 12px=””>Sample SizeMean Pain ScoreStandard Deviation of Pain ScoreNew Medication6030.317.52Standard Medication6053.857.44Because procedures can be more complicated in older patients, the investigators are concerned about confounding by age.
