A bottling company uses a filling machine to fill plastic bottles with cola. The bottles are supposed to contain 300 ml.

In fact, the contents vary according to a normal distribution with a mean μ =298 ml and a standard deviation σ = 3 ml.

What is the distribution of the mean content of a random sample of 100 bottles?

For instance, the label on a can of beets says it has x amount of iron, x amount of vitamin B12, etc.

How is this determined, and who does the testing? Is it a government agency or a private one?

What would be the procedure for getting a new food item tested to determine its nutritional content?
