1. Imagine if you are developing a hydride generation method for the determination of dissolved arsenic in groundwater. As part of the method validation, arsenic spiked groundwater sample was analyzed TEN (10) times repeatably. Given that the spiked concentration of 274.7 ng kg-¹ and the measured mean of 269.42 ng kg-1 with a standard deviation of 1.75 ng kg-1: (a) Test whether there the proposed hydride generation method give significant bias in the measurement results when α=0.05. Given that tc = 2.262. (t = 9.54) (b) Did the repeatability significantly better than 1% RSD? Given that Fc = 2.707.
