Go to stat-reg/distr -> invNormal(3) from there you can enter the percent you want, mean, and standard deviation and it will give you the z-score

To convert an x value to a z-score, the formula is:
(x value - mean)/standard deviation

Example: We have a number of height measurements that have a mean of 65.25 and a standard deviation of 2.84. One value is 68.5. To convert it to a z-score: (68.5-65.25)/2.84 = 1.144

Hope this helps!

Hi,
Use the [a b/c] key.
7 [a b/c] 11 displays 7u11. Numerator can have up to 6 digits. Denominator can have up to 3 digits
7[1 b/c] 11 [a b/c] 19 displays 7u11u19 meaning 7 and 11/19. The vaiois numbers can have up to three digits each, but the total number of digits must be less than or equal to 8.

The key combination [2nd][d/c] toggles display between mixed numbers and improper fractions.
The key combination [3rd][F<=>D] switches between fraction and decimals. (Not all decimals can beconverted to fractions: see limitations above).

Hoe it helps.

Hi,
There is a dedicated key for the function. The key is labeled as on the third line of the table below. You enter a positive number, press the key and then hit [=]. Hope it helps.

On the TI-36X there is no rooftop key, there is a yx key. This key is two keys below the on button. To use it, put the number in, press the yx key, put the exponent in, press the equal button.

### Anyone know how I can do Absolute Value on this?

The quick way to determine absolute value is to square the value and take the square root of that.
So on the TI, with the value on-screen, just push these 2 keys in sequence (they are right next to each other):

### I lost my user manual

Texas Instruments has the guidebooks for many of their calculators on their support page. http://education.ti.com/en/us/guidebook/search/scientific-calculators is the best starting point.

I hope this helps.

### Which calculator is better the TI 36X II(either batery or solar) or teh casio fx-115ES, the price its not a concern its the properties and functions of each one. im gonna study for engineer,and my TI...

Hi,
I would certainly upgrade my choice to the FX-991ES. It can do (numerical) integrals, derivatives, it has 40 physical constants (instead of 8). It can do unit conversions, and the Natural display is a real pleasure.
Don't get me wrong, I am no TI calculator basher. I have just bought the TiNspire, AND TINspire CAS. I have a TI92, a TI83, Ti BA 35Solar.
If you do become an engineer, the calculators you might want to use (not during the exams) are the TI 89 Titanium, HP49G+/HP50G, the Casio ClassPad 330. You see I recommend the TI89 Titanium because there is a wealth of Engineering programs written for it.

Hope it makes your decision easier.
