A supplier contract with a manufacturer requires that component returns be transacted in the ERP system within 12 hours. An analyst at the manufacturer thinks that the supplier is no longer meeting the contract requirements. The analyst has collected a sample of 95 transactions with a mean of 11.4 hours. The standard deviation is 2.5. Complete the hypothesis test using an alpha of 0.01 and select the best statement of the conclusion supported by the results of your hypothesis testing analysis.
