Dear Folks- I have no knowledge of what is an adequate number of samples to take for an analysis from a total of 20,000 bottles of 1 quart from two runs that are each of 10,000 in number. I want to get an idea of the quality of the product at a reasonable confidence level 95% so that the product can be verified as acceptable for the marketing and the consumer.

1. Is a randomized sampling of each lot in order?

2. What number of samples should be tested for validation?

3. What is the best software out there that is easy to use and learn with?

Many thanks for your help and ideas. Don
