In a ready-mix plant, cylindrical samples are prepared and tested periodically to detect any mix problem and to ensure that the compressive strength is higher than the lower specification limit. The minimum target value was at 42.0 MPa. The following compressive strength data were collected: All in Mega-Pascal (MPa) 41.8, 38.3, 42.5, 39.6, 42.5, 39.3, 41.2, 40.9, 39.8, 41.6 42.9, 43.4, 39.9, 44.7, 45.1, 43.9, 42.4, 41.7, 41.1, 42.1 Calculate the Arithmetic Mean, Median, and Standard Deviation.
