Question

Over the past 5 years, the mean time for a warehouse to fill a buyer’s order has been 25 minutes. Officials of the company believe that the length of time has increased recently, either due to a change in the workforce or due to a change in customer purchasing policies. The processing times (in minutes) were recorded for a random sample of 15 orders processed over the past month.
Do the data present sufficient evidence to indicate that the mean time to fill an order has increased?
