The seven scores listed here are axial loads ( in pounds) for the first sample of seven 12 oz aluminum can. An axial load of a can is the maximum weight supported by its sides, and it must be greater than 165 pounds, because that is the maximum pressure applied when the top lid is pressed into place. At the 0.01 level of significance, test the claim of the engineering supervisor this sample comes from a population with a mean that is greater than 165 pounds.
