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.
