Anterior cruciate ligament (ACL) injuries occur most frequently in planting and cutting sports such as basketball, soccer, and volleyball. National Collegiate Athletic Association injury data show that female athletes injure the ACL more frequently than their male counterparts do. A sports medicine professor wants to test this claim. He surveyed 5 universities that had both men's and woman's basketball, soccer, and volleyball and asked them how many grade 3 ACL tears they had during the past 5 seasons. Using the following results, are women at greater risk than men for ACL injuries? (Use 0= 0.01, one tail test) TI Women Men 1 1 35. Calculate the effect size using Cohen's d. 36. What conclusion can be made from these data? a. Reject the null; there was a significant difference b. Reject the null; there was not a significant difference Fail to reject the null; there was a significant difference d. Fail to reject the null; there was not a significant difference C. 43524
