# P-value with T scores on Casio fx-9750GPuls

I know the TI-83 and 84 have a tcdf function... but I have a casio and need to know how to find P-values using t scores.

In any scientific calculator log2(n) can be  calculated with either ln or log function as follows

Log2(n)= ln(n) / ln(2)

Or
Log2(n)=log(n) / log(2)

both will give nearly the same answers

SOURCE: absolutes on FX - 115ES

The absolute value button is "SHIFT", "Abs" (located on the "hyp" key)

Hello,
There is a function to calculate them for you.

In CAS, or Algebra or Tutor Modes, use the x! option
In Run-Math, press [OPTN][F6] to pan right, then [F1] to access the (PROB) menu then enter option number corresponding to x!
The way it works is as follows
number ! [EXE].
Due to memory limitations, you can calculate factorials of numbers up to 69.

Hope it helps.

Testimonial: "Thanks. Ended up finding it after searching around for 20 minutes. Appreciate the help though!"

SOURCE: i do not know how

Hey it is. Okay, so start with a equation: say, y = -(1 |x|). Now type y = -(1 , then press the [OPTN] button, next to the shift. Next press the [NUM] button or F5. The first menu button should be Abs or absolute value. When your done it should look like this. y = -(1 Abs (x)) then graph it.

### I do not know what a range is and where to find it on a Casio FX 9750GII Calculator

In statistics, the range of 1-var a data set is the difference between the largest value and the smallest. R=Xmax-Xmin
In functions: the range of a function is the interval (or the Union of intervals) of the real line where the dependent variable takes it values.
Ex: sin(x). Whatever the value of the independent variable x, the values of the function sin(x) are in the closed interval [-1,1]. The range of the functions sin(x), and cos(x) is [-1,1].
No use of a calculator for finding the range of functions.

### How do i calculate the normal probability value, give z-value, on casio fx-82ms

The fx-82MS does not have any built-in functions for calculating the normal probability distribution or its related values. You can calculate it using the defining function or any of a large number of approximations. Alternatively you can look up the values in a table.

Some advanced calculators have the functions built in, and programmable calculators can be programmed to give them. Sadly the fx-82MS is neither.

For more about the normal distribution, see http://en.wikipedia.org/wiki/Normal_distribution

### How do i use the fx-300es to graph

Sorry but you cannot do that. This is not a graphing calculator. However you can generate a table of values for your function (MODE TABLE) and use it to graph the curve by hand (pencil and paper).

If you need a Casio graphing calculator, one of the cheaper ones is the Casio FX-9750GII. Equivalent Texas Instruments calculators are the TI83PLUS/TI84PLUS.

Storing
1. To store numerical values in the variables A,B,C,D,X,Y and M you use the [SHIFT][RCL] key combination to access the (STOre) function.
2. In what follows [ key] is the physical key and (key) is the SHIFTED key
3. ex: store the value 13 in variable A
4. 13 [SHIFT][RCL] (STORE) [(-)] (A)
5. The calculator displays 13 --> A on top line and 13.000.. on bottom line.
Recalling
• To recall a value stored in a variable ex: recall value stored in variable A
• Press [RCL][(-)] (A)
• Calculator displays A on top line and 13 on bottom line.
If you need to use the variables A,B,C,D,X,Y, and the = sign to create an expression to be solved with the solve( function you must press the [ALPHA] key

=: [ALPHA] [CALC](=)
A: [ALPHA][(-)] (A)
B: [ALPHA][ 0 ' "] (B)
X: [ALPHA][ ) ] (X)
Y:[ALPHA][S<=>D] (Y)
etc.

### Casio fx-7400G PLUS cubic solver?

Hi,
First let us repair the terminology.

1. You can evaluate any expression (find the value of any expression for a particular value of its variable).Store a value in the variable, say X. Key in the expression and press [EXE].
2. You can consider your expression(should not contain a relational operator such as =, greater than, less than, greater than or equal to, less than or equal to) to be a function Y1(x) = expression and graph it, or generate a table for it. You will have several values of the function calculated at various points.
3. You can set your expression equal to 0 and find the particular value(s) of the variable (the unknown) that make the equality TRUE. That is called solving an equation.
I am not sure that it has a solver (solving an equation or an inequation) but you can always draw your expression as a function and explore the graph (SKTCH) to locate the roots (or zeros) of the functions (the values of the variable where the function equals zero.) That is called solving graphically.

Hope it helps.
Thank you for using FixYa and for rating this solution.

### How to find general anti-derivative Problems in Casio fx-115ES... I get the message syntax error, and also when the anti-derivative is bounded I get my answers in decimal form, i dont want decimal form......

Hello,

I assume that by anti-derivative you mean the integral. I believe that you can only calculate definite integrals with this calculator. A definite integral requires that you specify the function e.g ln(x), the variable, x, the numerical value of the lower limit, 0.5 and the numerical value of the upper limit , say 2.
Try this: INT(sin(x),x, 0, pi/2)
This calculator can only give numerical values of definite integrals. If you want to perform symbolic calculations, you shoul look towards some other, more sophisticated Casios Casio ClassPad 330, or the TI Voyage200PLT, or the TI89Titanium. etc.

Hope it helps
