The following results were obtained when two sets of items were subjected to two different treatments Xand Y, to enhance their tensile strength. Treatment X was applied on 400 items and 80 were found to have gained in strength. Treatment Y was applied on 400 items and 20 were found to have gained in strength. Is treatment Y superior to treatment X?
