A biosensor was developed to measure the concentration of aqueous arsenic. To determine the accuracy of the sensor, the sensor was tested against a standard reference solution of known concentration. The concentration measured by the new biosensor can be considered accurate if the standard deviations for the concentration determined by the biosensor and the accepted, known concentration of the reference solution are not significantly different. the standard deviations for the concentration determined by the biosensor and the accepted, known concentration of the reference solution are not significantly different, and calculated < ttable. the accepted, known concentration of the reference solution falls outside the 95% confidence interval for the biosensor results. the accepted, known concentration of the reference solution falls within the 95% confidence interval for biosensor results.

concentration of aqueous arsenic. To determine
the accuracy of the sensor, the sensor was tested
against a standard reference solution of known
concentration. The concentration measured by
the new biosensor can be considered accurate if
the standard deviations for the concentration
determined by the biosensor and the
accepted, known concentration of the
reference solution are not significantly
different.
the standard deviations for the concentration
determined by the biosensor and the
accepted, known concentration of the
reference solution are not significantly
different, and tcalculated < ttable.
the accepted, known concentration of the
reference solution falls outside the 95%
confidence interval for the biosensor results.
the accepted, known concentration of the
reference solution falls within the 95%
confidence interval for biosensor results.

A young researcher was evaluating a standard method for determining the methylmercury content in blue fin tuna using high performance liquid chromatography (HPLC). She determined the standard deviation (?)(s) for the method to be 0.440.44 ppb and assumed that ?s was a good approximation of ?σ . As a test, she used this method to evaluate the methylmercury content in a National Institutes of Standards and Technology (NIST) standard and determined the unknown amount to be within 0.210.21 ppb (?)(μ) of the known mean with 99% probability. How many replicate measurements of the NIST standard did the researcher perform?
