1 This empirically derived table for a sample size of 1 is suitable only for use in the concrete strength analysis in 903.03.
2 Numbers in the body of the table are estimates of lot percent defective corresponding to specific values of “Q,” the Quality Index. For values of “Q” greater than or equal to zero, the estimate of percent defective is read directly from the table. For values of “Q” less than zero, the table value must be subtracted from 100.

1 Numbers in the body of the table are estimates of lot percent defective corresponding to specific values of “Q,” the Quality Index. For values of “Q” greater than or equal to zero, the estimate of percent defective is read directly from the table. For values of “Q” less than zero, the table value must be subtracted from 100.
