20. Which of the following statements regarding detection limits (D.L.) are false: (1) Only~1% of measurements of a blank are expected to exceed theD.L. (2) If the analyteconcentration is right at the D.L., then one is only 50% confident to say that the sampledoes contain analyte. (3) If the analyte concentration is right at theD.L., then one is 99%confident to say that the sample does contain analyte. (4) Measurements showing resultsbelow D.L. can suggest the sample does not contain analyte. (5) The probability of beingfalse positive is ~1% for samples containing no analyte. Your answer:
