Need to know how to use the calculator to solve confidence intervals for the mean

Your angle unit is set to degrees. If you do not change the Xmin and Xmax window dimensions to say -180 to -90 for Xmin, and 90 to 180 for Xmax you will not see much of the features of the graph; In the default interval Xmin, Xmax the curve is a staright line.

The 86 has more memory. It also has some advanced calculus capabilities the 83 doesn't. However you're much more likely to see examples for the 83 in textbooks and other references.

First, connect the two calculators with the unit-to-unit cable.

Prepare the receiving calculator: press 2ND [LINK] F2.

Select the item to send on the sending calculator: press 2ND [LINK] F1 F2. For each program you want to send, navigate to it using the up/down arrows and press F2. Press F1 to send.

Three possibilities:

1) You entered an argument with an inappropriate dimension.

2) You entered a matrix or vector dimension < 1 or > 255 or a noninteger.

3) You attempted to invert a matrix that is not a square matrix.

If you need further help, please specify the exact problem you're trying to solve.

1 - .93 = .07/2 = .035

Texas Instruments TI-86 Statistics How-To Information The following instructions should allow you to calculate the mean and standard deviation using a TI-86 calculator.

1. Press STAT
2. Select EDIT
3. Enter data into a list: [2.32 ENTER 2.43 ENTER 2.39 ENTER, etc.] Continue until all data have been entered. (use arrows keys to go to the y value, if any)
   
4. EXIT until you reach the main ("blank") screen. (If you try to calculate while you're in the data menu, it thinks you're still trying to enter data!)
5. Press STAT
6. Select CALC
7. Select OneVa
8. Select LIST, NAMES, xStat(F2), Press ENTER
9. The calculator provides Max, Min, Mean, Standard Deviation, Sum, Sigma, etc. You will be primarily interested in the Mean and Standard Deviation (sx).

Most likely you're trying to graph a function while you have the stat plot turned on. Turn off the stat plot and try it again.

Hello,
Here is how you make graphics of functions on the TI 86. The screen captures are from the TI86 Manual by texas Instruments.
Chapter 6 oth the manual concerns Grpahic tools.

Hope it helps.
