Normaldistributions can easily be dealt with using the TiNspire and the Statistics Made Easy
App from www.TiNspireapps.com.
If you are to compute the area under the Standard Normalcurve as shown in the problems in the image below:
Just navigate to Normaldistribution in the Menu :
Now enter mean = 1 and std deviation = 0 as we are dealing with the StandardNormal Distribution.
Next enter B as shown given in problem .88 and A can be any number below -3 … out comes the answer
Alternatively, you could have entered .88 for A and found the answer in the 3. line instead of the 2. line
Additionally, InvNorm type problems (given area find z value ) can also be solved
