Which calculator can do a "normal probability plot"?



Hi,

    Anyone know which calculator can do a "normal probability plot"?  I have
a TI-86 with the advance stats module, but I don't see how it can do it.  If
no calc can do it, any suggestions on how to program it?

Info about "normal probability plot":
------------------------------------------------
How do we know if a normal distribution is a reasonable model for data?

Probability plotting is a graphical method for determining whether sample
data conform to a hypothesized
distribution based on a subjective visual examination of the data.

Probability plotting typically uses special graph paper, known as
probability paper, that has been designed for the hypothesized distribution.

To construct a probability plot, the observations in a the sample are first
ranked from smallest to largest.  Observations are plotted against their
cumulative frequency.
