A quantitative analysis for an analyte gives a mean concentration of 12.6 ppm. The standard deviation due to the method, sm, is found to be 1.1 ppm, and that due to sampling, ss, is 2.1 ppm. By how much does the overall variance change if sm is improved by 10% and ss is improved by 15%?
A method for the detection of morphine is used to generate a calibration curve in which the assay response (y) is plotted versus morphine concentration (x, in mg/L). This gives a straight line with a slope (m) of 0.241 and a y-intercept (b) of 0.011, where y = mx + b. The slope of this line has a standard deviation of ±0.007, and the standard deviation of the intercept is ±0.006.
