Sampling, Statistical Quality Control, Index Number Analysis

This assignment solution addresses key concepts in business statistics, focusing on sampling techniques, statistical quality control, and index number analysis. The solution begins by calculating mean debtor balances using stratified and systematic sampling methods, comparing their effectiveness and constructing confidence intervals. It then delves into statistical quality control, analyzing initial and additional samples using control charts to assess process stability. Finally, the solution explores index numbers, including egg price indices, CPI changes, and export receipt movements, providing calculations and interpretations. The analysis includes tables and figures to illustrate the findings, demonstrating an understanding of statistical principles and their application in business contexts.
