question archive The manager of a fast food restaraunt wants to determine whether the population mean waiting time to place an order ha changed in the past month from its previous value of 37 minutes A random sample of 64 orders shows a mean waiting time of 40 minutes It is known from past experience that the population standard deviation of waiting time is o= 115 minutes Formulate and test the appropriate hypotheses using the p-value approach What is the p-value for the test? Should the research firm reject the null hypotheses at a=005? What conclusion should they make?
