Some people seem to believe that you can fix anything with duct tape.Even so, many were skeptical when researchers announced that ducttape may be a more effective and less painful alternative than liquidnitrogen, which doctors routinely use to freeze warts. The article "Whata Fix-It: Duct Tape Can Remove Warts" (San Luis Obispo Tribune, October 15, 2002) described a study conducted at Madigan Army MedicalCenter. Patients with warts were randomly assigned to either the ducttape treatment or the more traditional freezing treatment. Those in the duct tape ground wore duct tape over the wart for 6 days,then removed the tape, soaked the area in water, and used an emeryboard to scrape the area. This process was repeated for a maximum of 2months or until the wart was gone. Data consistent with values in thearticle are summarized in the following table: Treatment n Number with WartSuccessfully Removed Liquid nitrogen freezingDuct tape 100104 6088 Do these data suggest that freezing is less successful than duct tape inremoving warts? Test the relevant hypotheses using a significance levelof 0.01.
