Tomato sauce is packaged in a bottle designed to hold a nominal 16 oz of product. Eight samples of 4 bottles were randomly inspected. The results are listed in the following table:

1. Calculate the sample means and sample standard deviations.
2. Calculate the control limits for -chart and s-chart. What can you say about this process?
3. Estimate the population mean and standard deviation.
4. Estimate what percentage of products from the current process will meet the specification?
