The accepted value (mu) for a standard sample of chloride was 34.63 percent chloride. Triplicate analysis of this material by a new procedure yielded a mean value of 34.71 and an estimated standard deviation of 0.04. Do these data indicate the existence of determinate error in the new method with 95 percent confidence level?
