An Experiment Was Performed on a Certain Metal to Determine

question 81

Short Answer

An experiment was performed on a certain metal to determine if the strength is a function of heating time. The 95 percent confidence interval for the average strength of a metal sheet when the average heating time is 4 minutes is from 4.325 to 5.675. Therefore, we are confident at α = .05 that the average strength of this metal heated for four minutes is between 4.325 and 5.675 pounds per square inch. Do you agree or disagree with this statement?
