In a study on hemophilia A, a sample of 30 known carriers were measured for (AHF activity) and (AHF antigen). Another independent sample of 22 known noncarriers were also measured for these two AHF variables. In order to determine whether carrier status can be determined by these two variables, researchers first need to establish whether there’s a difference between the two groups (carrier vs noncarrier). (4pts) Describe briefly what procedure would be appropriate for this task, along with any assumptions that would need to be made. (3pts) Would the procedure in A be considered paired or independent?
