Standardizing a Normal sampling distribution
... Central limit theorem: When randomly sampling from any population with mean m and standard deviation s, when n is large enough, the sampling distribution of x̅ is approximately Normal: N(m,s/√n). ...

... Recovery is used for seasoned samples, since the component concentration level was not determined independently of the test method. It is defined as the calculated mean for the seasoned sample with a standard addition of the component minus the mean for the seasoned sample, divided by the actual amo ...

Mean Analysis
... 1. Take a random sample of size n. 2. Calculate the confidence interval based on your sample. 3. Check if the confidence interval is small enough. If it is too wide, decide a proper width. 4. Assuming the sample standard deviation will remain the same, use the equation for confidence interval to est ...
