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) TT Women Men 4. 1 1 35. Calculate the pooled variance (Sp2) for the data. 36. Calculate the estimated standard error (s(M1-M2) for the data. 37. Calculate the observed t statistic for the sample. 3524
