For a concentration technique, stotal is given as 19.31 ± 0.035, smb is 0.22 ± 0.008, and ka is 0.154 ± 0.007 ppm–1, where stotal is the signal, ka is the method’s sensitivity for the analyte and smb is the signal from the method blank. if we want the overall percent uncertainty to be 2.6%, which statement is false below?
group of answer choices:
a. improving the signal’s uncertainty will improve the overall uncertainty
b. uncertainty in the method’s sensitivity dominates the overall uncertainty
c. we must improve the uncertainty in ka to ±0.004 ppm–1
d. none of the above
