Of course I worked the problem before posting here, but after talking to my friend I'm not sure I did it right.

This is what I had.

Going off of the breakdown of percentages on a bell curve,

34.13%+6.795%=40.925, then you take 50%+40.925%=90.925, then 100%-90.925%=9.075%

This is where I ended, but then my friend said that she got something different. I can't remember the exact number she said. Please help me.
