Out of 100 respondents I expect 7 to see the number on this sign. All male!

Your question has very two different meanings depending on if people click to see your comment or not.  

Thanks bambi. One way to test the validity of iroon.com surveys is to put up questions with previously known stats and see if iroon results are similar to the known numbers. In this red-green color blindness test, the 7%  of our men who are red-green colorblind will see a number. By the way, women are far less likely to be red-green color blind. Has to do with the gene sitting on the X chromosome where men have only one while women have a "backup."
