That would be the one ;)

I have an 89...anyone know if there's a function to go between z-scores and 
percentages (of area of the normal curve) on the 89?

I was trying to figure out what the function was for a normal curve was 
yesterday and tried solving for equations like y = e^(-a*x^(2b)) and y = 
a/(cosh(bx)^2)...didn't occur to me that it was y = a*e^(-b*x^2) ;)  Oh 
well...
