      We usually want the cumulative distribution function (cdf) for the normal distribution. The probability distribution function (pdf) would be useful to graph the normal curve in Y=, but Shade_t already does that. Inverse t. There is no function corresponding to invNorm for the t-distribution, but you can use the TI-84 equation solver. MATH 0 ...
