Use the data set workout_exam2.sav to answer the final questions.  A researcher from the Exercise and Science Department is interested in preferences for different types of workouts and the impact on health. Data from 60 FAU undergraduate students were collected, 20 of whom prefer cardio workouts, 20 who prefer weight lifting, and 20 who prefer a program which contains both cardio and weight lifting exercises (workout). The researcher recorded the participants’ weight, their sex, their preferred type of workout, whether or not they had a trainer, and their overall health using the Hunter-Joseph Health Scale, where 1 = poor health and 10 = excellent health. The researcher is interested in the effects of (1) trainer and (2) workout type on participants’ health (HJHS score). Perform a statistical test to examine whether having a trainer and workout type influence health.  Upload your output file showing this test.
