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.
