I think im supposed to get the lower and upper limit but I've forgotten how to do that outside of statcrunch.

This is what I've done so far and I think im confusing myself. Too many steps here.

2.576 squareroot .8(1-.8)/470= 0.048.

Not sure what to do now. Please help. I can get it if I can only remember the correct steps.
