Question
A researcher performs atomic absorption measurements of 5 standard solutions containing iron. A reference material was then measured to have a 5.1 ± 0.1 mg/L amount of Fe. If the reference material was stated to contain 5.0mg/L, determine if the measured value is different at the 95% confidence level. [Fe] measured = 5.1 mg/L Ux = 0.1 mg/L [Fe] known = 5.0 mg/L 2.) The researcher tests a water sample to measure an Fe content of 0.6 ± 0.1 mg/L. If the regulated limit of Fe in water is 0.4 mg/L, determine if the measured water sample exceeds this limit using statistics. [Fe] measured = 0.6 mg/L Ux = 0.1 mg/L [Fe] limit = 0.4 mg/L
