Tiger Tools company, a subsidiary of the Drillmore Industries, was about to launch a new product. In this regard, the Production Manager asked her assistant Jim Peterson to evaluate the capability of the existing equipment used in the process. He proceeded to obtain eighteen random samples and the results of these samples were put in a table. His subsequent conclusion after analyzing the data would be that the process was not capable. This was on the basis of the width specification of 1.44 cm.
Given the ambition that the company had, of introducing the new product, using the same equipment, this analysis proved a major setback. This is despite the fact that the Production Manager had hoped that the new product would

Similarly, in this case, the level of certainty of the findings depended on the underlying variability of the data and size of the sample used. The more variable the samples are, the greater the associated with the estimates. Having a smaller sample size deprived the company of the ability to detect the differences that would have otherwise have been affected by the random aspect of the study. This is because any difference in the data obtained would have been within the confidence intervals set by the company, therefore making it difficult to detect (Joglekar, 2003).
Also, it is equally important to consider the manner in which the samples were selected. In order for the data to reflect the true status and potential capability of the equipment in question, an unbiased sample selection technique ought to have been used. In this case, there has not been any specific mention of the process of selecting the samples.
It is common practice that sampling is used to inspect the quality of products, especially in companies that massively manufacture products. For example, if an inspector controls quality of products in China, he or she is not able to check the whole batch. Therefore, he or she probably checks a proportion of the entire batch. However, owing to the fact that the products are sold far and wide across the globe, the sampling of products for inspection is just as of importance as any other process in the manufacturing and processing of such products
