Sample Size Determination and Statistical Hypothesis Testing for Core Centration in Press Coated Tablets


A novel statistical approach to evaluate the manufacturing quality of press coated tablets in terms of the centering of their core is presented. We also provide a formula to determine the necessary sample size. This approach is applied to real data.
