# Need Keystroke Help!

I just bought a Ti BA 2 Plus Pro as a back-up for my 12c to use on the exam. Can someone be so kind to share with me the key strokes to calculate the correlation coefficient on the Ti using this example of assumptions: standard deviation (Ra) .0529 standard deviation (Rb) .1114 Cov (Ra, Rb) .0058 It’s suppose to = .9842 *Just for the record, I know how to do these on the 12c the long way : .0058 enter, .0529 enter, .1114 x /. I just need a little help solving this on the Ti, please.

strokes: 0.0058 divide ( 0.0529 times 0.1114 ) =

That was easy, but I would’ve never figured it out on my own, THANKS!

why would you want to learn how to use a new calculator 1 month before the exam? good luck!

“I just bought a Ti BA 2 Plus Pro as a back-up for my 12c to use on the exam” Dude - this sounds like a bad idea. Buy an extra battery for the 12c or an extra 12c if you are that paranoid.

You could also do: strokes: 0.0058 divide 0.0529 = 0.1096 divide 0.1114 =0.9842 Also if you have Schweser check out the online video intro to the BAII
