First fifteen results, in N/mm², of a M25 concrete at a site are 21.5, 22, 21.9, 18, 19, 20, 19.8, 14.5, 17, 18.2, 16.1, 18.8, 20.9, 21.2, 20.2. The test result corresponding to the 16th sample is 21.9 N/mm². Assuming the quality control of the concrete samples to be very good, is this concrete acceptable?
