Researchers concerned with the effect of loud music on teenagers' hearing found that there wasn't evidence of a higher hearing loss among teenagers who frequently attended rock concerts.They based this conclusion on a test using α = 0.05.Would they have made the same decision at α = 0.10 and α = 0.01?
Hearing Loss
A partial or total inability to hear sounds in one or both ears.
Loud Music
Sounds with high decibel levels that can potentially cause hearing damage or disturbance.
Alpha

Final Answer :
At α = 0.10 they reach the decision only if the P-value is > 0.10.We know only that it's > 0.05.But we know that it's > 0.01,so at α = 0.01 they reach the same decision.
