Determine, at the 95% confidence level, if there is an outlier in the following measurements of the concentration of sodium sulfate from a water supply. Assume the measurements have such high precision that you can safely keep 5 significant digits in your intermediate calculations. Keep in mind that you are simultaneously testing two possibilities with the absolute value Grubbs test: that the value is either above or below the critical threshold. Only check for one outlier. Show your work and state your conclusion. (19, 45, 54, 42, 44, 46) ppm
