Question:

Refer to the Composites Fabrication Magazine (Sept. 2004) study of the strength of fiber-reinforced polymer (FRP) composite materials, Exercise 2.47. Recall that 10 specimens of pultruded FRP strips were mechanically fastened to highway bridges and tested for bearing strength. The strength measurements (recorded in megapascal units, MPa) are reproduced in the table. Use the bootstrap procedure to estimate true mean strength of mechanically fastened FRP strips with a 90% confidence interval. Interpret the result.


Data from Exercise 2.47

Fiber-reinforced polymer (FRP) composite materials are the standard for strengthening, retrofitting, and repairing concrete structures. Typically, FRP strips are fastened to the concrete with epoxy adhesive. Engineers at the University of Wisconsin–Madison have developed a new method of fastening the FRP strips using mechanical anchors. (Composites Fabrication Magazine, Sept. 2004.) To evaluate the new fastening method, 10 specimens of pultruded FRP strips mechanically fastened to highway bridges were tested for bearing strength.
