Actually, the world knows, but the opinion varies widely.
Suprisingly the debate isn't over how she did singing, it's about the length of time she took to sing.
In fact, SB Nation reports that the length of the national anthem is one of the most popular Super Bowl prop bets.
They reported that the over/under was set at 2 minutes and 20 seconds.
If you watch the end of her performance, you can see the confusion:
At the end she sings the word "brave" twice.
When she finishes the first "brave" she was under the 2:20 mark. If you're counting the second "brave" she was over the 2:20 mark.
It seems that deciding which is correct depends largely on the rules of where you bet.
Here we go: Bovada is paying UNDER on National Anthem, and BetOnline is paying OVER. Discrepancy on validity of Gaga's extra "brave" at end.

While I didn't make a prop bet on the national anthem, I know plenty of people did. I hope it worked out in your favor.
So what do you guys think, should the second brave be counted towards the over/under?
