Question about Texas Instruments TI-89 Calculator

# I keep trying to do a 2-proportion Z test in my calculator (by going into stats, test, 2-prop Z test) and i enter all the info (correctly) and it comes out with error; Domain. what am i doing wrong?

First, could you clarify the calculator you're using? From your description, it doesn't sound like at TI-89 but rather a TI-83/84.

Second, it seems as if you're not entering correct info. Why don't you post at least one set of data that leads to the domain error?

### How do i calculate the standard deviation

for 1-Var statistics
Press [MODE][3:STAT] [1:1-VAR]. You are ready to enter values in the X column.
Enter a number and press [=]. Cursor jumps to second number to enter.
Keep entering numbers and pressing [=] till all numbers are in. Press the [=] key after the last one.
Press [AC] key to clear the screen.
Press [SHIFT] [STAT] (above digit 1.) then [5:Var]. Screen displays the statistical variables 1:n ;2: x bar; 3: x sigma n; 4:x sigma n-1.
Press the number corresponding to Referable you want, ex 1:n . The variable appears on screen. Press [=] and it will be displayed.
To display another variable press [SHIFT][STAT][5:Var][ 1,2, 3, or 4] .

To access the sum of squares sigma x^2 and the sum of data sigma x press[SHIFT][STAT][4:SUM] then [1: for sigma x^2] or [2: for sigma x]. Press [SHIFT][STAT][6:MinMax] to access minX and maxX.

For 2-var statistics
To perform 2 variable statistics you press [MODE][3:STAT] and any of the other regression options (except 1:1-Var). A two column template opens where you enter the X and Y values. When finished entering data, press [SHIFT][STAT][5:Var]. to access the different statistics. you should be able to recognize what each variable means.

### I don't know anything about physics or statistics or anything like that so I cannot do a test problem. :-( But I am in physics now and the professor said we needed a calculator that can do 1 and 2 variable...

Do not go buy another calculator because this one does 1-var, 2-var, as well as some regression models, and some distributions.
For 1-var and 2-var statistics read on.

### ERR: INVALID DIM (That's the error message I receive every time I try to graph an equation)

Hello,
[2nd][MEM][7:Reset][1:All ram][2:Reset] [ENTER]. Screen shows RAM cleared. Clear the screen and use [Y=] to enter the functions you want to graph.
Hope it helps.

### Graph function is giving an error

Your stat plots are on, and may not be filled out/ correctly filled out.
go to [Y=] and go up to the stat plots ([Plot 1], [Plot 2], [Plot 3] ) and turn off the ones that are "ON" ( highlighed black w/ white text.) and press [ENTER] on the ones that are on and the problem is no more.

### TI 84 Silver Plus

I'm not sure, but it probably gives the error because one of the values you entered isn't valid. It's too big or too small.

If this doesn't solve the problem, please let me know.

### Standard deviation

Here goes if you still need this...

STAT, EDIT, put information into L1 if only one variable stats, but put info into L1 and L2 if it is frequency table stats.

Then choose Stat, over to CALC, 1, enter...if 1 variable stats then press enter again. If frequency table stats, then choose STAT, over to CALC, 1, 2nd, 1 [L!], 2nd, 2 [L2], enter.
