Product description

1. To check the results of the determination of ethanol in wine by the enzymatic method, gas chromatography was used. With repeated analysis of the same sample by two methods, the following data were obtained: by the enzymatic method 13.1; 12.7; 12.6; 13.3; 13.3% ethanol; gas chromatographic method 13.5; 13.3; 13.0; 12.9% ethanol. Can we assume that for a 95% confidence level, the enzymatic method gives the same results as the gas chromatographic method?
