Hi i want to calculate regression in casio fx-3600pv???please help me

Here is what I gather from the picture of the faceplate.
You choose the standard deviation mode (SD) by pressing MODE 3.
You might have to choose 1-Var or 2-Var. (not sure, but 1-var for sure)
You enter a data item followed by the DATA (RUN) key. Keep entering data and pressing RUN.
While in SD MODE, if you press the 1 key you get the avregae xbar, if ****** you get the sum of squares of the entered data. Looking at the digit keys, They all have statistical markings: (A, B, and r) are for regression analysis, (7,8, 9). 2 has the population standard deviation sigma n x, 3 the sample SD, etc. That should get started. And please, experiment. There are not many variations, on th statistical theme on scientific calculators.
Hope it helps.

HP 49G+ trying to dowloading a surveying program from Unfortunately Xmodem Transfer cannot locate my calculator. I have ran through the troubleshooting hints, to no avail. Thanks, Brian

Why not use the SD card slot on the calculator? Use an SD card formatted in FAT 26 or FAT 32 of not too large capacity, say up to 2 GB. Using a computer, transfer the program on the card and store it at the root of the card: DO not store it inside a folder.
Once the program is on the card, remove the card from the computer and insert it in the SD card slot of the calculator. Turn calculator on and use the file explorer of the calculator.
Press Green Left Shift followed by the APPS key to enact the Files explorer. Navigate to the root of the SD card, copy your program and drop it in one of the three internal memories. IRAM, ERAM or FLASH

How to get the Z normal distribution values?

Note that this I'm using a Casio fx-991MS calculator.

I'm also assuming you're asking about the z value i.e. P(t)

You first need to go to SD mode, which is done by pressing Mode button twice where you'll get the choices as follows:
1 2 3
Press Numeral 1. you should see a small sd icon on the top of the display after you press 1.

Now enter Shift key + '3' i.e. Shift + DISTR and you'll get the options as follows:

P( Q( R( t->
1 2 3 4

Choose whichever is required.
Hope this is what you were asking about.

Hello, I have a casio fx-9860 GII, and the sd card is stuck in it... how can I fix it?

To extract the SD card from its slot, you press with a finger on the edge. It should pop out a bit. Pull it out.
If it refuses to pop out, either you did not press hard enough to feel it move inside or ejection mechanism in calculator is defective.

My sentry caculator is displaying SD in the window how do i turn it off

I do not know this calculator, but from my experience, it is likely that your calculator is configured to do statistical calculations (Standard Deviations) hence SD. Change the computational mode to COMP and the SD will probably be replaced by an abbreviation for the MODE in effect.
Sorry not to be able to help you more, but what do you expect if you hide the identity (or the species) of your calculator.

Hope it helps.

How to convert fraction to decimal

You can convert between Standard Form (with fractions and pi) or Decimal form by using the "S<->D" button. Use Mode 1 if you mostly prefer fraction answers and you can use the SD button to convert to decimal or use Mode 2 if you mostly prefer decimal answers and use the SD button to see the fraction.
I hope this helps and good luck!

1st time set up for sd memory card on sharp xe-a203 cash register, i keep getting error code e-sd-99. i've retried it 3 times and keep getting this error. the card is 128mb.

According to my manual, the cards should be formatted on a Windows PC. Insert the card into any computer and wait for it to be recognized. Access the card's memory by clicking on the icon in the "My Computer" (or equivalent) window. BE SURE THERE IS NOTHING ON THE CARD THAT YOU WILL LOSE. This process will erase everything on the card. Right-click on the card's icon. Click "Format." Set formatting options to FAT memory. Set the allocation size to 16. Start formatting. Double-check your manual to be sure for the specifics on your exact model of calculator.
