The article €œWind-Uplift Capacity of Residential Wood Roof-Sheathing Panels Retrofitted with Insulating Foam Adhesive€ (P. Datin, D. Prevatt, and W. Pang, Journal of Architectural Engineering, 2011:144€“154) presents a study of the failure pressures of roof panels. Following are the failure pressures, in kPa, for five panels constructed with 6d smooth shank nails. These data are consistent with means and standard deviations presented in the article.  

Find a 95% confidence interval for the mean failure pressure for this type of roof panel.
