A83: ARGH! Statistics help




I have my math final tomorrow, and my calc is pulling some weird shit on
me:

ok, look at this, I ask it:
normalcdf(0,1.3
it returns:  .4031994501.
That's correct, but when I ask it:
invNorm(.4031994501
it returns:  -.2450742993.

What am I doing wrong?!?!?!  I should read 1.3!  I need to know this before
12:00AM...(just under 5 hours from now)  I'd REALLY appreciate some help.

I know its not ASM, and I know its statistics...but :)

Thanks.

James.
