Lies, Damn Lies, and...
I just saw a Pepsi commercial that claims that "56% of people think that Diet Pepsi has more cola flavor than Diet Coke."
Considering that the "null hypothesis" would be "50%", that's one of the least impressive endorsements I have ever seen on television.
(Sure, since we don't have access to the full details, that may be a test that had more than two options. But still... as endorsement goes, that is tepid.)
