Hypothesis Testing

 

You have been given the final results of this study. What are your conclusions?  Describe your conclusions and how you derived them.

  • RQ: To what extent does our new composite material improve load-bearing capacity of aircraft wings?
  • Ha: Aircraft wings constructed with the new composite material will have greater load bearing capacity than aircraft wings that are not constructed with the new material.
  • H0: There is no difference between composite aircraft wing load bearing capacity and other aircraft wings.
  • Population 1 characteristics: Sample Size=50, Mean=61, SD=4
  • Populations 2 characteristics: unavailable for reference
  • Hypothesis testing probability results:  p=.034

 

Please note you are given the null and alternative hypotheses as well as the p-value based on the hypothesis test.  You need to interpret the p-value and state the conclusion in the context of the hypothesis being tested.

Here is the practical rule. If the p-value is less than 0.05 the typical level of significance then the null hypothesis is rejected.  Otherwise there is no evidence to reject the null hypothesis.
