Margin or error on the ti-84?

Rhino

Any easy way to calculate E on the ti-84? I can do it manually, but it's a lot of button mashing. I would assume/hope there is just a simple function that I can punch in a few values and have it do it for me.

I've never used APPS, is there a downloadable (free and legal) program that would do this?

There is no dedicated button for calculating a margin of error. You can certainly run whatever confidence interval you are attempting, subtract your upper bound from your lower bound and divide by two.

yeah I'm assuming that's what he considers a lot of button mashing...You could write a simple program that would let you input the lower and upper bounds and then output the margin of error?

Calculating a CI is a program on the TI84; one would hope writting down the two numbers and then performing basic arithmetic wouldn't be a strain or button mashing.
