I have a ti-89, does anyone know how to calculate percentages of teh normal model on it? I am not sure what the function is, and using the table in the back of my book is a pain. The problem's I mean are, for example-(adsbygoogle = window.adsbygoogle || []).push({});

given N(80,5) what percentage of the data is above 92 given the information fits a normal probabilty distribution. note i don't have the 89 titanium so i may not have certain programs. Thank you
