Research Question: To what extent does ERAU's new composite material improve, if at all, the load-bearing capacity of aircraft wings?
Ha:Allaircraft wings constructed with the new composite materialwillhave a greater load-bearing capacity than aircraft wings that are not constructed with the new material.
H0:Allaircraft wings constructed with the new composite materialwillnothave a greater load-bearing capacity than aircraft wings that are not constructed with the new material.
Sample summary data before new wing composite material: Sample Size = 50, Sample Mean = 62 lb/sq. in., Sample Standard Deviation = 4 lb/sq. in.
Sample summary data after new wing composite material: Sample Size = 40, Sample Mean = 64 lb/sq. in., Sample Standard Deviation = 3 lb/sq. in.
Significant level = 0.05
What is the p-value?
Answer the research question.
What is the effect size, i.e., "large", "medium", or "small"?
