Questions needed to solve are under the table

term Question 2 (12 marks) The paper "No Evidence of Impaired Neurocognitive Performance in Collegiate Soccer Players" (American Journal of Sports Medicine [2002]:157-162) compared collegiate soccer players, athletes in sports other than soccer, and a group of students who were not involved in collegiate sports with respect to history of head injuries. The table shows a 3X4 two-way frequency table of independently al selected random samples of 91 soccer players, 9 non-soccer players, and 53 non-athletes, as reported on medical history questionnaires of 240 students. Number of Concussions 0 2 3 or More Row Marginal Concussions Concussion Concussions Concussions Total Soccer Players 45 25 10 91 Non-Soccer Athletes 68 15 96 Non-Athletes 45 53 Column Marginal Total 158 45 22 15 240 Is the number of concussions tied to the type of athlete? Provide a detailed null and alternate hypotheses (equations AND complete sentences). Note that you will also have to create a table of expected values. (4) Calculate the test statistic (3) Neatly draw the diagram showing the critical zone and non-critical zone, and relevant critical test statistic and actual test statistic (3) Clearly write a conclusion at the 5% significance level.
