A manufacturing company is studying the time it takes to complete and deliver an order in one of their product lines. In the past, it was taking 140 days on average to fill orders but they recently redesigned the process hoping it might reduce delivery times. Historical data shows that the delivery time follows a normal distribution with a standard deviation of 60 days. In fact, the first 25 orders processed after the change was made were filled in 100 days on average. Construct a test to see if the redesign helps the company reduce the delivery time (Use = 0.1).
