Refer to the Composites Fabrication Magazine (Sept. 2004) study of the strength of fiber-reinforced polymer (FRP) composite materials, Exercise 7.100. Recall that 10 specimens of pultruded FRP strips were mechanically fastened to highway bridges and tested for bearing strength. The strength measurements (recorded in mega pascal units, MPa) are reproduced in the table. Use the bootstrap procedure to test (at α = .10) whether the true mean strength of mechanically fastened FRP strips exceeds 230 MPa.
