On the TI-36X Pro, Q(x) can be done using the Normalcdf dialog with mu=0, sigma=1, LOWERbnd=x and UPPERbnd=1e99. Q⁻¹(a) can be done using the InvNormal dialog with area=1-a, mu=0, and sigma=1. (The area is set to 1-a because it uses the area to the left. (The HP-33E Inverse Normal Integral program in the Statistics Applications book uses the area to the right.) Alternatively, set area=a and negate the result.)

The calculation is done in the special dialog and cannot be done inline on the home screen. The result of the calculation can be saved to one of the eight variables for use in further calculations.

The distribution dialogs menu is reached from the home screen by pressing 2nd stat-reg/distr key sequence and selecting the DISTR tab:
