4. A new method for the determination of mercury in fish was tested against a N.I.S.T. standard to determine if there was any bias (determinate error) in the new technique. The N.I.S.T. standard fish sample was certified to contain 13.55 ppm Hg. The results of six analyses by the new method gave a mean value of 14.15 ppm and s.d. = 0.42 ppm. Does the new method give accurate results at the 95% confidence level?
