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,
42.5,
41.2,
40.9,
38.3,
42.9,
39.3,
