Some people seem to believe that you can fix anything with duct tape. Even so, many were skeptical when researchers announced that duct tape may be a more effective and less painful alternative than liquid nitrogen, which doctors routinely use to freeze warts. An article described a study conducted at a medical center. Patients with warts were randomly assigned to 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 was gone. Data consistent with values in the article are summarized in the following table. Treatment n Number with Wart Successfully Removed Liquid nitrogen freezing 103 60 Duct Tape 101 88 Do these data suggest that freezing is less successful than duct tape in removing warts? Test the relevant hypotheses using a significance level of 0.01. (Use pnitrogen − pduct tape.) Find the test statistic. (Round your answer to two decimal places.) z = Find the P-value.

Question

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 was gone. Data consistent with values in the article are summarized in the following table.

Treatment	n	Number with Wart Successfully Removed
Liquid nitrogen freezing	103	60
Duct Tape	101	88

Do these data suggest that freezing is less successful than duct tape in removing warts? Test the relevant hypotheses using a significance level of 0.01. (Use p_nitrogen − p_{duct tape}.)

Find the test statistic. (Round your answer to two decimal places.)

z =

Find the P-value. (Round your answer to four decimal places.)

P-value =

State your conclusion.

Fail to reject H₀. We do not have convincing evidence that the proportion of people for whom the wart is successfully removed is less for the liquid nitrogen treatment than for duct tape treatment.Fail to reject H₀.
