Research Scenario #$1($Q$1-6$: $26$ pts content $/9$ pts format$)$: Research has found that physicians often ignore complaints in older patients that they take more seriously in younger patients. In an effort to reduce this prejudice before it becomes too ingrained, a researcher designs a study to have fourth$-$year medical students see videos of $10$ patients $($who are really actors$)$ a month apart. In one sequence of the $10$ videos, an actor is made up to look about $70$ and talks about being retired, and in the other sequence of the $10$ videos, the same actor is depicted as his own age $(30).$ The actor presents similar complaints in each video. Students are randomly assigned to the order of viewing these two sequence of videos a month apart. After viewing each of the videos, the students list the questions they would ask the patient, their diagnosis of the complaint$($s$),$ and their rating of concern for the health of the $$patient$$ on a $15-$point scale, with higher score
