Extracted text: Porlorming a new analytical proceduro in triplicale, the percontage of copper in an alloy was found to be 20.54%. with a standard deviation of 0.04, to. Calculate the 95% reliability limits for the mean value. b Express the confidence interval with 95%. c. What is the approximate probabiity of obtaining a value of 24.12% copper? d. If the true amount of copper, obtained by other means, is assumed to be 20.75%. 1. What is the absolute error of the now method? 2. What in the rolalive error of the neww mothod?
