Milk samples Dairy inspectors visit farms unannouncedand take samples of the milk to test for contamination. If the milk is found to contain dirt, antibiotics, or otherforeign matter, the milk will be destroyed and the farmreinspected until purity is restored. Would simple random sampling be appropriate for select-ing farms for inspection? If so, explain how it would be done. If not, explain why it is not appropriate.

The Covid-19 pandemic has many experts commenting on the science associated with the virus - origins, vaccines, monoclonal antibodies, masks, social distancing.  It is important to consider what the experts say, but to also evaluate their statements.  We will start with the scientific method.  I want you to outline the scientific method from what you have been taught in previous classes.  You can list steps, parts, process, short descriptions, whatever.  If not taught in previous classes, then you will make your best guess about it.
