An experiment was performed on a certain metal to determine if the strength is a function of heating time.95% 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 $\beta$ = .05 that the average strength of metal heated for four minutes is between 4.325 and 5.675 pounds per square inch.Do you agree or disagree with this statement?
A)Agree
B)Disagree

Quizplus · Accepted Answer

The given confidence interval suggests that we can be 95% confident that the true population mean strength of the metal when heated for 4 minutes lies between 4.325 and 5.675 pounds per square inch. As the confidence level is quite high (95%), we have strong evidence to support the given statement. Therefore, we agree with the statement.
