How do I find p (z<2.5) on my TI-84 calculator?
Press (2nd) (Distr) then choose normalcdf.If you are using a TI-84 PLUS CE, you will be able to fill in the blanks like in the middle screen image. If you have an older TI-84 or TI-83-Plus, you have to remember the order in which the information must be entered.Here are sample images for the probability that z is < 2.5:As you might remember, Z scores have a mean of zero and a standard deviation of 1, so typing those numbers is optional, as shown in the third image.Some of the newer calculators have a CATALOG HELP function, as shown in green.By the way, if you know someone who is ABOUT to buy an 84 calculator for Statistics class, tell them to buy the Texas Instruments TI-84 PLUS CE Graphing Calculator, Black (Frustration-Free Packaging) because it has features not available in the older calculators. For example, if you wanted to find the Z-scores between which 88% of the population falls, on the CE, you could do it this way:As you can see, invNorm(.88, 0, 1, CENTER) gives both answers. On the older calculators, you have to mentally calculate that 0.88 is centered between 0.06 and 0.94, then calculate each value separately (or remember that one is the inverse of the other).Another reason to recommend the CE even over the Silver Edition, is the “Cut and Paste” and “Undo Clear” commands that are new features of Operating System 5.0. For more information about the newer CE calculators and OS 5.0, see this web page:Why the TI-84-Plus-CE is better than all the other TI-84's (if your CE does not yet have OS 5.0, upgrade at education.ti.com)
I took the batteries out of my TI-84 graphing calculator and now it won't turn on. How do I fix this?
I suppose you refer to the situation that your TI-84 won’t turn on when configured without external power but loaded with batteries.This is relevant, because, as a rule, for electronic reasons nearly all calculators must be loaded with batteries to function properly, even when powered by an external adapter.In case your TI-84 is configured without external power but loaded with batteries, and still doesn’t start, this may help:take all batteries outcheck: all batteries correct type? (should be 4x AAA)check: all batteries fully charged?check: battery contacts clean?press ON (the reset the innards of the machine)replace batteries into correct position (!)press ON.If still no show, try this:take all AAA-batteries out.unscrew back-up battery lid (located under the AAA-battery cover)take back-up battery out (carefully)check: back-up battery fully charged?check: contacts clean?press ON (to reset the innards of the machine)replace back-up battery and AAA-batteries.press ON.If still no show, an ultimate last resort might be:take all batteries out (back-up and AAA)short-circuit the back-up circuit (via the visible contacts) and AAA-circuit (via the visible contacts). ‘Short circuit’ just with a small wire like a probe of your multi-meter. Do not apply any voltage!If still no show: your TI-84 probably is broken.Note: unlike many other calculators the TI-84 lacks a hardware reset button, which is a bit of a pity in situations like these.
