2. We would like to investigate the incidence of concussions among athletes. Samples of soccer players, non-soccer athletes, and non-athletes are collected. 0 # of Concussions 1 2 ≥ 3 255 11 10 83 8 3 50 5 0 Soccer 45 N-S Athletes 68 15 Non-athletes 45 To see whether these three types of individuals have the same distribution, conduct a chi-square test of homogeneity at a = 5%. State (i) the degree of freedom, (ii) the expected frequency count of each cell and (iii) the conclusion of the test.
