A Biosensor Was Developed to Measure Aqueous Arsenic Concentration

A biosensor was developed to measure aqueous arsenic concentration.To determine the accuracy of the sensor,the sensor was tested against a standard reference sample.The biosensor results agree with the standard reference sample when:

A) the accepted value falls outside the 95% confidence interval for biosensor results.
B) the accepted value falls within the 95% confidence interval for biosensor results.
C) the standard deviations for the biosensor and accepted value are not significantly different.
D) the standard deviations for the biosensor and accepted value are not significantly different and t_calculated < t_table.
E) the standard deviations for the biosensor and accepted value are significantly different and t_calculated < t_table.
