Hey guys. I've been procrastinating a little bit, and with the test tomorrow, I'm having to write out the whole equation (which takes about 10 minutes and is about 3 miles long). I need to know how to plug it into my TI-83 so I can actually do all of the problems on my test tomorrow. I know how to get to the standard deviation. I get to:
2nd - Stat, then scroll to MATH, and then go down to StdDev(
I don't know what to plug into the parenthasies from StdDEV(
If any of you can help, it'd greatly be appreciated.
