State gas chromatographic vs spectrophometric approaches

Reference no: EM13161551

Consider a nitrite (NO2-) analysis for rainwater samples. Gas chromatographic (GC) vs. spectrophometric approaches were compared with the following results as means ? standard deviation. Do these methods agree with each other at the 95% confidence level? Be sure to show all calculations and all assumptions. Rainwater: 0.069 ? 0.005 mg/L (n=7) (GC) 0.063 ? 0.008 mg/L (n=5) (spectrophotometric)
