You have been given the final results of this study. What areyour conclusions? Describe your conclusions and how you derivedthem.

RQ: To what extent does our new composite material improveload-bearing capacity of aircraft wings?

Ha: Aircraft wings constructed with the new composite materialwill have greater load bearing capacity than aircraft wings thatare not constructed with the new material.

H0: There is no difference between composite aircraft wing loadbearing capacity and other aircraft wings.

Population 1: Aircraft wings constructed with a new compositematerial.

Population 2: Aircraft wings in general.

  • Confidence Interval: 95%
  • Population Mean = 59.945, Sample N=50, Sample X-bar=61, SampleSD=4, p=.034
