Normalcdf function

Ad

Sorry, the TI-30x doesn't have the cumulative normal probability function built-in.

SOURCE: square roots

One way is you get square root by raising to the (1/2) power. For example square root of 16 is

16^(1/2).

You can use this method to get the other "roots" as well e.g. 1/3, 1/4, etc.

SOURCE: how do you divide the denominator into the numerator on the TI-30

Yes, you hit the yellow 2nd key and then the back arrow (it says F D above it in yellow.) It's the last key on the bottom of the left hand row.

SOURCE: How to do nPr or nCr on TI-30x Solar (scientific calc.)

If you have an older version on the TI30x Solar (not TI30Xa or newer) then you must use a different key sequence for nPr/nCr.

52 [2nd][x/y] 5 [2nd][nCr] gives 2598960 (the x/y button is above the Pi symbol on my version).

8 [2nd][x/y] 3 [2nd][nPr] gives 336

This took me forever to find out, so hopefully it will help someone!

You will find the description of all potential errors in the manual.

It means the calculator is current set to the degrees mode. Trigonometric function depend on how you measure the angle. The most common units are degrees, radians, and grads. To change the mode on the 30Xa, press the DRG key to cycle through them.

The normalcdf function takes three arguments: the z value, the mean, and the standard deviation. In the "standard" case the mean is 0 and the standard deviation is 1. Thus, try calculating

normalcdf(-.1923, 0, 1) .

normalcdf(-.1923, 0, 1) .

You can download the TI-30Xa guidebook from the manufacturer's web site at

http://education.ti.com/calculators/downloads/US/Guidebooks/Detail?id=6132

The TI-30Xa replaced the TI-30X within a year. The only enhancement was the added Constant key.

The TI-30XII, introduced about five years later, is a significantly different calculator, incorporating, among other things, a two-line display.

There is a quick guide here which should help http://education.ti.com/downloads/guidebooks/scientific/30xii/30xiiqrg-eng.pdf

So you press 2nd Function , select 1-Var or 2-Var (for paired datat) then enter your data pressing down arrow after each and Enter to finish then press STAT / VAR to see the various variables

Please give me a thumbs up if this helped

I had the same problem. However, I learned: Press the upper light blue button, Reading: 2nd and then press: the ON button. This method shuts mine off.
