Super Hero Stratified Sampling - What's The Story? In tough economic times the Super Heroes of the world are trying to make their operations more efficient. To do this they have decided to survey both members of the public and villains as to what works best. There are far too many of each to survey all of them so have decided to take a sample from each group. It must be proportional so have decided to perform a stratified sample. Can you help our heroes calculate the numbers from each group that they should choose?
