UHC Investment Bank is the owner of a Houston area project and TRUE TEST is the project materials testing lab. Hard Concrete Group is the concrete supplier and they don't believe that TRUE TEST is property curing concrete cylinders on site. Hard Concrete Group hires XYZ to spit fresh concrete samples with TRUE TEST during a paving placement. TRUE TEST casts 6" X 12" cylinders on a hot August Saturday afternoon and leaves the cylinders uncovered out on the site in the sun. TRUE TETS returns to pick up their cylinders on Wednesday afternoon. XYZ also casts 6" X 12" cylinders but, immediately after casting, they carefully move the cylinders into a deserted yet air conditioned trailer. XYZ picks up their cylinders the next day. At an age of 7 days, will the TRUE TEST or XYZ cylinders result in a higher average compressive strength
