Calcs with Probability Distributions

[sguth]

Hi everybody,

I'm a statistics professor, and I've long been annoyed that non-graphing scientific calculators don't have probability distribution functions. More college students take statistics than other college-level math courses, and scientific calculators have had trig functions since the 70s (absolutely useless for most students), but still no probability distributions.

Exceptions: The TI36X Pro has cumulative normal/inverse normal functions. The HP 10BII+ has cumulative and inverse normal and t-distributions. Pretty cool, but its a business calculator.

Is there any other scientific (non-graphing) calculator that does cumulative/inverse normal, t, chi-square, and F distributions????

Thanks in advance,
Scott Guth
