Question

You have been given the final results of this study. Describe all t distribution conclusions with the given data and how they were derived.

• RQ: To what extent does our new composite material improve load-bearing capacity of aircraft wings?
• H_a: 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: Aircraft wings constructed with a new composite material.
• Population 2: Aircraft wings in general.
• N=50, M=61, SD=4, p-value =.034

Answer 1

Solution

We have given that

• H_a: 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.

N=50, M=61, SD=4, p-value =.034

let $\alpha$ = 0.05

Decision : Since the p-value =.034 < $\alpha$ = 0.05 level of significance so we reject the null hypothesis.

Conclusion : We have sufficient evidence to conclude that 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.
