These questions are not necessarily designed to have a 'right' or 'wrong' answer -- there are various shades of grey. The purpose is to get you thinking about the statistics involved. You can do this at any level of statistics (ignore any parts which seem too complicated)

Can you think of concrete examples (which may or may not be simple) where the statements in the questions do or do not happen?
