A researcher is looking at the relationship between playing contact sports in high school and osteoarthritis among men in their forties. Among a random sample of 150 men between the ages of 40-49 who played contact sports in high school, 44 reported they had osteoarthritis in at least one knee. Among a random sample of 150 men aged 40-49 who did not play contact sports in high school, 16 reported having osteoarthritis in at least one knee. Does the proportion of men with osteoarthritis differ by whether they played contact sports in high school? Run the test at a 5% level of significance.
