Mean separations will be calculated by an approved statistical method . If the test result indicates that there is a ninety - five percent ( 95 % ) or better probabil­ity that the other IFN ALFA - N3 performs more favorably with respect to the clinical response being tested, then said IFN ALFA - N3 shall be deemed, for purposes of this Agreement, -11 - to be than the lSI IFN ALFA - N3
