The average service time at cheeseplate restaurant

Reference no: EM13240496

The average service time at CheesePlate Restaurant is 3.5 minutes with a standard deviation of .04 minutes. A new order system claims it can improve service time. A sample of 49 orders revealed a mean service time of 3.4 minutes. Does the claim about the new order system hold true?
