Question

The federal Aviation Administration requires material used to make evacuation system retain thir strength over the life of the aircraft, In an accelerated life test, the principal material, polymer-coated nylon wave, is aged by exposing it to 158 degree F for 168 hours. The tensile strength of the specimens of this material is measured before and after the aging process. The following data (in psi) are recorded: An article in the Journal of Aircraft (Vol. 23, 1986, pp. 859-864) described a new equivalent plate analyses method formulation that is capable of modeling aircraft structure such as cranked wing boxes and that produces results similar to the more computationally intensive finite element analyses method. Natural vibration frequencies for the cranked wing box structure natural frequencies are shown here. Do the data suggest that the two methods provide the same mean value for natural vibration frequency ? Use the P-value approach.
