    Confidence interval vs. expanded uncertainty

    Hi, I'm struggling with the difference between confidence interval and expanded uncertainty. I understand a confidence interval around the mean. For example, a 95% confidence interval around the mean says that if N samples were taken 100 times and a confidence interval was recalculated each...

    Tolerance Interval for Standard Uncertainty

    Hello all, Here's my question. I'm reading an old work document written back in the 80s. The purpose is to calculate a 95/95 one-sided tolerance interval for a parameter of interest. To do this, they use the following equation: x + 1.645*S where S = sqrt( (dF/dx * zx * sx)^2 + (dF/dy * zy *...
