Some people seem to believe that you can fix anything with duct tape. Even so, many were skeptical when researchersannounced that duct tape may be a more effective and less painful alternative than liquid nitrogen, which doctors routinelyuse to freeze warts. An article described a study conducted at a medical center. Patients with warts were randomly assignedto either the duct tape treatment or the more traditional freezing treatment.Those in the duct tape group wore duct tape over the wart for 6 days, then removed the tape, soaked the area in water,and used an emery board to scrape the area. This process was repeated for a maximum of 2 months or until the wart wasgone. Data consistent with values in the article are summarized in the following table.Number with WartTreatmentSuccessfully RemovedLiquid nitrogen freezing10260Duct Tape10388 Do these data suggest that freezing is less successful than duct tape in removing warts?
