me competitive advantage of some small American factories such as In Tolerance Contract Manufacturing lies in their ability to produce parts with very narrow requirements, or tolerances, that are typical in the aerospace industry. Consider product with specifications that call for a maximum variance in the lengths of the parts of 0.0004. Suppose the sample variance for 36 parts turns out to be s² = 0.0005. Use a = 0.05, to test whether the population variance pecification is being violated. Ho: sigma squared is less than or equal to 0.0004 ₂: sigma squared is greater than 0.0004 est statistic- 38.75 (to 2 decimals, if required) × The p-value is greater than 0.10 Do not reject the null hypothesis v The product specification does not appear to be violated. V . Use Table 11.1.
