Finding Sample Variance and Sample Standard Deviation A quality control manager at a manufacturing company is responsible for ensuring the consistency and reliability of a production process. The manager is concerned about the variability in the measurements of a critical product dimension. That's why he has collected measurements of a critical product dimension from a sample of items produced in a manufacturing batch. The measurements show variations from the expected dimension. Calculate the sample variance and sample standard deviation of the measurements. Follow each step as given, provide the appropriate inputs, and solve. Measurements 12.5, 12.8, 12.3, 12.6, 12.7
