Need to no how to find Type 1 error for statistics on TI 83 plus

If some of the lists are missing press the STAT button then select SetUpEditor and ENTER to restore all of them (without data, of course.)
If the statistical plots are turned OFF you can turn one of them back ON again. Press SHIFT Y1= to access STAT PLOTS. Press 4:Plots Off. A good habit to avoid problems. After you turn all plots OFF, you must turn one of them ON if you intend to draw statistical graphs. You can for example Turn Plot1 ON.

1. To do so Press SHIFT Y1=, select say 1:Plot 1 ENTER.
2. Highlight ON and press ENTER.
   
3. Press DownArrow to move to line TYPE
4. Then you can set the plot type. You have 6 choices. Use the left/Right arrows to select one of the 6. The selected plot type icon will remain highlighted when cursor is moved.
5. Use DownArrow to move to XLIST line and select the x-values LIST. etc.
6. When finished Press 2nd QUIT to exit the stat plts configuration settings.

One statistical value that may be of interest to you is the R, R^2 coefficients. To have it displayed (if the regression model has it), you must set DiagnosticsON.

Press SHIFT 0 to enter catalog. Press x^-1 key to jump to the first command that starts with D.
Scroll down to reach DiagnosticsON, highlight it and press ENTER then ENTER.

you mean edit - just do 2nd , then window, walla - use your arrows to navigate and reset numbers, sometimes you need the table setup for the statistic and probability calculations - get the ti for dummies, and there is a statistics ti 84 book also that helps a lot.

get the TI 84 for dummies book, and check the statistic functions - they are fantastic - got me an A in statistics - once you start using them, you must practice- a function for everything!!

You have to turn all statistical plots OFF before you draw function graphs. Press [2nd][Y=] to open the statistical plot configuration screen. Press [4:PlotsOFF] and then [ENTER]. When calculator answers DONE you are ready to draw function plots.

Having gone over a month with no response, I assume this is no longer a problem.

Press [STAT] to open the Statistics editor. From the menu that displays, select PlotsOFF and press [ENTER] twice. The calculator answers "Done".
Open the [Y=] editor to enter the functions to be drawn. Use the Trace ONLY after the graph has been displayed.

To clear any message without necessarily removing the conditions that yield the error press the CLEAR button.

You must deactivate the statistical plots. If you do statistical graphs, the graphing is reconfigured in a way that happens to be incompatible with regular fuction graphs.

1. To deactivate the statistical plots.
2. Press [2nd][Y=] to access the (STAT PLOT) menu.
3. Press [4:PlotsOff][ENTER].
4. Calculator displays Done.
5. You are ready to draw the function graphs.
   

Easy:
1.) Turn it on ("ON" button)
2.) Hit the "STAT" button
3.) Hit the Right arrow key Twice
4.) Hit the down arrow key once or hit the "2" button
5.) Enter your Data into List one (L1) OR Right Arrow once and "ENTER" to just enter your statistics

To just Enter the Statistics:
Down Arrow once and Enter:
Hypothesis mean
Sample Mean
Standard Deviation
Number of Tests
and Either (not equal to)Ho , <Ho , or >Ho
Then either hit Calculate or Draw

If this is confusing try this website:

You can't simply enter 7x+9=30 into the calculator, there is a way to calculate what the x is but its been a few years since I've done these..
