[citation][nom]MDillenbeck[/nom]Went to the Scientific America article to find out more - $1, $5, $10, $20, and $100 bills were samples.If we are to assume an equal number of each bill, then this gives a sample size of 2.6 bills per denomination per city. N = 2.6 is no where near the needed sample size.Where were these samples taken? At banks, from store registers, out of volunteers' wallets? Why so few?My favorite response from that article's comments was by ifitzme:Wouldn't that be an interesting confound![/citation]
They got the bills from prostitutes and dealers...
It's definatly accurate!
