Confidence interval for calibration curve. To use a calibration curve based on n points
Chapter 4, Problem 4-36(choose chapter or problem)
Confidence interval for calibration curve. To use a calibration curve based on n points, we measure a new value of y and calculate the corresponding value of x. The one-standard-deviation uncertainty in x, sx, is given by Equation 4-27. We express a confidence interval for x, using Students t: where t is taken from Table 4-2 for n 2 degrees of freedom. A calibration curve based on n 10 known points was used to measure the protein in an unknown. The results were protein 15.22 (0.46) g, where sx 0.46 g. Find the 90% and 99% confidence intervals for protein in the unknown. C
